yemen is divided between a north controlled by the houthis, backed by rain and a south dominated by supporters of ousted president abd-rabbu mansour hadi. now the country's foreign minister is appealing for help from the gulf cooperation council to hold back the houthi advance. >> no one wants to be pulled into direct action on the ground. the majority consider it a final option. if we felt compelled and the ministers necessary, we would go ahead with the proposed plan. >> reporter: this is what a g.c.c. force could look like originally set up to respond to military aggression against saudi arabia united arab emirates and others, it is a force of 100,000. it made conflict of every day men, this fight. here threatening houthi forces

their power place, and as zeina khodr reports, their support is key to a deal on a national unity government. >> it has long been criticized for acting as an independent state. it has been accused of using military force for political gain and labelled as a stronghold. misrata denies all of that. there's no doubt that this city in central libya is not only powerful within its borders, the influence extends beyond. >> misrata is located to the east of tripoli. to a large extent the government relies on the libyan dawn military alliance to stay in power. and it is the military and political power of the alliance which seized the capital last year. >> misrata has thousands of fighters constituting one of the largest armed groups. it acquired massive quantities

of weapons. since misrata, just like all of libya's armed forces didn't disarm nor did they unite with other forces. recently violence has escalated, there seems to be a growing realisation among the g.n.c. that there is no military solution to this conflict. >> according to the g.n.c. there were voices who i considered as extremists to a degree. fortunately there are a lot of people who recognise that the only way to make peace in libya and move towards democracy is to have dialogue with all sides. >> reporter: but they also have a red line. the libyan dawn alliance is at war with general khalifa haftar's forces who back the government in the east. misrata and allies accused

it could be used arbitrarily. if anyone found anything they deemed to be offensive, they could use the law to file a police complaint. if the person making the complaint was someone of influence or wealth police would follow through with an arrest. one of the most infamous cases happened in 2012 after the death of a leader leading to a city-wide shutdown. a woman questioned why a city had to come to a stop. another liked it on facebook and both were arrested by the police. now, critics say abuses luke that were common -- like that were common in the country. petitions were failed saying it was too vague and draconian, which the supreme court agreed with can indians put anything they like online? >> well within reason. law for the internet has been struck down there are other

laws protecting criminal behaviour. this goes to the more broader issue of freedom of expression in india. many people complained that there has been a crackdown overall in the country, not just online. many small groups are considered extremist by some. they used thugs and goons to intimidate people who say or post online things they don't like or agree with. while indians have more legal freedom now. they have to be mindful of social and cultural consequences of what they put on the internet our correspondent live from delhi. lots more to come in al jazeera. including binyamin netanyahu - he says sorry. the israeli prime minister regrets his remarks about palestinians.

message for his own people. >> the differences between the two countries bring shadows over us. repatriations are not just material it's an ethical issue. it's not just about greece but for the greek and german people who spilled a lot of blood to deal with naziism. >> for her part angela merkel roped repeated a message. we want greece to have growth coming out of high unemployment and we want to make sure that this high youth unemployment can be overcome and structural reforms are necessary for this solid budgets is necessary, and a functioning glass is necessary. i think that is clear for both countries. >> beyond all this is the reality that german economic strength is helping to keep

greek afloat. costing many billions. >> and now a growing number of people say they have had enough. >> we can help to solve the problems, but the greeks must want this too. to give them more billions makes greek's woes worse in the long run. you buy time no one can expect that we will ever see that money again. >> but buying time can only go so far. because alexis alexis tsipras indicated greece could default on its debts within weeks. which helps explain why he came to the german capital to try to build bridges with the leader of europe's economic powerhouse. on the face of it there has been no tangible progress. the venezuela president is trying to gather $10 million signatures for a petition to end sanctions imposed by the united

squares along the country asking president obama to resign it. >> we'll defend the country with our lives. president obama made a mistake, firing in the wrong direction. we are a peaceful country, we want to keep it that way. we are not going to allow him to deal with us as he pleases. >> government critics see little use behind the order. they see the law as a godsend that gives the government the perfect instruction. abroad regional allies like ecuador, argentina closed ranks behind venezuela. in a special meeting the bloc denounced president obama's decision. who the winner is in the latest impasse remains to be seen. >> what does this diplomacy seek. >> it's not clear if they wand a confrontation or reconciliation especially with the actions

leading up to the american summit. where important issues should be scuffed, and especially of a -- discussed, and especially of an historical moment. it looks like they want to divert attention to confrontation. >> this is the first time cuba will be attending the summit of america. it's anticipated the focus will be the reproachment of the island and the united states. the recent diplomatic spat may shift the focus elsewhere. >> with renewed diplomatic ties between the u.s. and cuba the region could see the end of half a century of geopolitical stand offs. many fear a few beginning. >> the sound of gunfire rings out across many u.s. cities on a regular basis. a system that detects the sounds is helping police catch the criminals as jacob ward now explains. >> reporter: in many ways oakland california is the perfect place to live.

fire was detected in the shooting of two police officers. it may also reveal an understanding. official estimates are based on 911 calls, which are tied to homicides. gun fire may go unreported when it doesn't hit anyone. when someone fires a gun, people call 91120% of the time. the -- 911, 20% of the time. the first challenge is four out of five times no one knows it happened except the person pulling the trigger. >> reporter: there has been thousands of non-fire-related firing. shots data suggests such incidents may be 80% with 25-50 times more rounds fired. >> if the american population knew how many shooting incidents there are in which bullets are flying through the air, and little kids are listening to

gunfire five, 10, 15 times a night. i think the reaction about the gun debate would be a little different. >> with 300 sensors in place between brooklyn and the bronx new york it may be the beginning of a new understanding that the sounds of violence have on public health. researchers say it can have a life-lock impact on a child's health. >> children are sensitive to the repeated stress act vasion. their brains and bodies are developing. high doses of adversity, not only affect brain structure and function, they affect the developing immune system. developing hormonal systems. and even the way our d.n.a. is read and transscribed. whether or not acoustic detention helps police in the city it may be revealing once
