to express anger at the results, but respect the police for the job that they are doing, by and large in most communities in projecting them. the attorney-general, at the same time, indicated that even though the officer had been found not guilty of any offense by the local authorities, a federal investigation will proceed, continuing with his behaviour, or examining his behaviour, but looking broadly at the conduct of the ferguson police department, which has been accused of discriminatory policies against blacks in various measures. and however it is - the question here is whether charges will be brought in this case against the officers for the police department and the by historical commaption that has rarely been

4:16 am
4:17 am
hello again. a reminder of the top story on al jazeera. the city of ferguson, missouri is trying to return to normal after a night of violence. this is a live picture from the town. protests broke out following a grand jury decision not to
4:18 am
indict a white police officer who shot and killed a black teenager in august. 29 people have been arrested this evening. after the grand jury announcement. u.s. president obama called for calm. in a nationwide address he urged americans to accept the grand jury decision. >> residents across jerusalem remain on high alert a week after 5 israelis were skilled in a synagogue. the incident followed weeks of back and fourth attacks in the city. jerusalem is gripped by anger and fear, a climate that is fizzible on the city's trams linking occupied east jerusalem with the west. andrew simmonds explains in the ancient city of jerusalem. this is no ordinary tramline. it follows a route of division between jews and arabs, running on what was part of the green line separating jordanian east
4:19 am
jerusalem with the israeli west, before the 1967 war. >> stop by stop this tram follows a modern time line of division and tragedy. the line links the occupied west with the east. it's a focal point for anger. here, now, there's a sense of frustration. of fear. >> that is not surprising. most places you look, there's a gun in site. newer people are getting on board now. the concrete ball ard is to prevent attackers crashing cars into crowds. two were killed here a fortnight ago. two weeks earlier, a woman and a baby were killed. in both attacks palestinian drivers were shot dead. >> there is fear when you get on the train. we have to reach a solution. we all live here, then and us. the train is ours and theirs.
4:20 am
the arabs have to understand that we are not the british. we are at home. they will never stop us. >> since the start of the incident there are fewer on the tram. we are setting out to work. we don't know what will happen on the way. anyone can harass us. the feeling is not good. it's scary. >> predictably at night the risks are higher. a few meters aa palestinian was snatched from outside his home in july by a jewish gang and burnt to death. it followed the murder of three israelis, and the cycle of violence started. this damage to the station, only the beginning of widespread rioting. here a short distance away there's the aftermath of
4:21 am
confrontation. rarely a night goes by without trouble. when will it stop. could it get worse before it gets better? >> god willing we hope the situation will go back to the way it was before. runs there is peace. they will feel safe, we will too. >> we are neighbours who have to live together. that's how it is. >> but is that wishful thinking. the tram heads west with no solid hope of it one day symbolizing the peaceful existence of jews and arabs. >> the foreign ministers of the gulf cooperation council are meeting in doha ahead of a summit next month. we go to doha and we are going there. what is expected, jamal? >> well, the fact that this meeting is taking place is seen as a good sign for break through
4:22 am
of the gulf countries, which have been uneasy to say the least. it follows a meeting in saudi arabia, where intermediaries from kuwait and saudis - qatar was essentially edged out so to speak of the gc c because of some of its stances. some were unhappy that doha took a different stance particularly with regard to egypt and its opposition to the practices of their military, and the crackdown on democracy over there. it seems come of those disagreements have been settled at least, and now this meeting is taking place and we are going to wait and find out if there'll be any other achievement for the meetings that will begin shortly in doha. >> thank you very much. >> jamal, to egypt where a

building has collapsed in cairo. at least 12 people have been killed. >> the building collapsed in the mataria district tuesday morning. others are thought to be missing under the rubble. egyptian president abdul fatah cysty has met european leaders. the situation is on the agenda in talks with the prime minister. abdul fatah al-sisi met pope francis at the vatican. al jazeera continues to demand the release of our three journalists who have been held in prison in egypt for 332 days. peter greste, mohamed fadel fahmy and baher mohamed were gaoled on false charges of helping the outlawed muslim brotherhood. they are appealing against convictions. world leaders who failed to reach a nuclear deal with iran.
4:24 am
are looking to persuade skeptics on both sides that an agreement cap be reached. a week of talks fizzled with the u.s. and allies declaring an extension on the deal. jonah hull reports from the austrian capital. >> reporter: the talks had broken up with that agreement, but secretary kerry and other ministers were involved in putting on brave faces. this is not the end of the road. >> today we are closer to a deal that would make the entire world, especially our allies and partners in israel and the gulf safer and more secure. is it possible that in the end we just want to ask at a workable agreement. absolutely. we are certainly not going to sit at the negotiating table
4:25 am
forever. absent measurable progress. but given how far we have come over the last year, and particularly in the last few days, this is not certainly the time to get up and walk away. >> in tehran, president hassan rouhani was upbeat. sooner or later there would be an agreement. >> we have not reached a final agreement. today things are quite different to three months ago. >> how much would have changed four months from now. by now, a framework agreement will be in place, or in seven month's time. this is it a process cloaked in secrecy watched by conservative skeptics on both sides, and in which deadlines many little. two missed, two new ones in place. we thought we were in for a repeat of geneva, negative
4:26 am
predictions up until the last moment. a deal emerges. that is not the case here. the question is whether the extension period. enough progress can be shown to have been made to convince skeptics on both sides of the process to carry on supporting it. >> it will be difficult for the president obama administration to convince the progress, to put more tan the table and bring about relief. what we know is significant gaps remain in negotiations to limit iran's ability to produce weapons grade materials. what we don't know and are not likely to be told is how far apart the two sides are. they have seven more months to succeed. up to now, they have failed.
4:27 am
there has been two separate explosions in the african capital. six army personnel were injured when a mini bus they were in was hit by a roadside bomb. some were arrested after throwing a hand grenade. we are also getting reports that three police men have been killed in loggar province the united states deputy secretary chuck hagel's resigned. the former republican senator has been pentagon chief since last year. he'll remain in his job until a successor is nominated. >> and a submarine is to dive into the antarctic sea to map how thick the ice is. british scientists hope their work will help to better understand the impact of global warming. our environment editor nick clark reports.
4:28 am
>> powering through in the name of science. a british antackic survey ice breaker heads south, its mission to measure the sea ice, crucial information for scientists in the context of climate change. the so-called seabed robot is deployed, weighing in at 200 kilos, and nearly 2 meters long, it's been designed by the woods hull graphic institute in the u.s. as it submerged into the icy water, the robot complex software fires up. they look down at the sea floor. this has an upward facing sonar. they are controlled remotely from on board the ship. maybe to perform detailed mapping. >> when we look at it on the
4:29 am
surface we see the blocks. >> it's hard to look at and see how thick it isment what we have here is a robotic submarine going under the ice. it will look from the bottom and give us a 2d map. >> the imagery is crunched with satellite data to create 3d. the underside of the size provide a rich tab low of information about its structure and how it's changing. >> we find that the area of sea ice is shrinking, and, therefore, we are trying to understand the process, of why the area is reducing. >> so far only a small area has been mapped. about the seize of 100 football pitches. scientists say it's an important step in making routine measurements to understand large-scale changes happening in antarctica

scomplrning welcome back to "techknow." ." marita, you took a look at meat or at least something that looks like meat. >> looks a lot like meat actually. americans, we love meat. we eat more of it than almost anywhere on the planet but it's extremely environmentally costly to produce. there are lots of meat alternatives on the market. there is a company based in california producing a product that they claim simulates meat very, very closely so you may not even be able to tell the
4:54 am
difference. so, i went and checked it out, put it to a taste test. so let's take a look. >> grilled, sautéed prosprocessed or packaged. america's obsession with meat is ferocious. we consume over 270 pounds per person per year. but now, the demand for meat is spreading to new global heights and experts predict we won't be able to sustain it. >> i would say we are already not doing it sustainability. we are crawing on the planet's resources more than we should be alone. >> the united nations estimates meat consumption will rise nearly 75% by 2050. the rising trend has triggered a new crop of meat alternatives helping to ease our reliance. >> here in california, we have a small town with the
