>> more and more of the eyewitnesss and residents in sanaa eye been speaking with and also government officials there believe yemen is really now on the brink of all out civil war. let me give you the most recent worrying development. in the past hour we've spoken to more residents in sanaa report more than 1,000 armed tribesmen that have entered sanaa late last night, early this morning. when asked why they were coming into the city they said they were there to support the leader of the hasha tribe, the most powerful tribe in yemen, the tribe engaged if street battles with president saleh's forces. more worries that more tribesmen are coming into a capital beset with so much chaos and fighting the last week. also i spoke to a government official early this morning and he's wondering why there's no more international mediation going on. even though president saleh has refused to sign a transfer of power deal in the past few months, government officials want the international community to step up. they're afraid if someone doesn't apply more pressure from the outside this fighting can continue for weeks or months on end. a lot of concern being expressed as to what's going on. the residents there, first you were hearing a lot of fear as to what's going on in sanaa. in the past several hours i'm hearing the mood is shifting to one of anger and they're upset. not just with the president but the family that controls the hasha tribe, fighting the government forces in the capital. they're very, very angry that this is going on. they want their city restored. they want peace in their neighborhoods. they're tired of hearing shelling and bullets ring out and they're worried for their safety and family's safety. zain? >> mohammed, it's difficult to know exact numbers, particularly as cnn isn't allowed inside yemen. what are your sources telling you about the latest death toll in yemen? >> there's been a lot of conflicting reports. we talked to medics, to eyewitnesss, to government officials. as far as sanaa we're hearing numbers as high as 40. now, tribesmen there are saying at least 20 of their tribesmen have been killed in fighting in the past couple of days. government forces are saying at least 15 soldiers and one army general have been killed. what we don't know is the correct number of civilians killed. it's very hard to get a handle on that number. everybody i speak with there is concerned this casualty figure is really going to go up once it calms down enough so an assessment can be made and real casualty figures can be counted. in taiz where there are government clashes, the u.n. put out a number in the last couple of days saying as many as 50 were killed by government forces in the past few days while they were peacefully protesting. there's been a lot of international condemnation at yemen's president because there's a fear the people that are out there trying to protest peacefully and demand the ouster of the president are being fired upon and getting killed. the yemen government of course denies these allegations. >> thanks, mohammed. a lot being said in the papers about this story. in britain the herald has a headline, yemeni capital rocked by series of explosions saying analysts are worried instability in yemen could embolden a local al qaeda wing that has attempted attacks on the united states and saudi arabia. gulf news has this headline, ending the yemen blood shed saying the way forward does not look like being an interim government based on a popular movement but more of a transfer to tribal or military leaders and even that is looking less likely as civil war looms. the guardian has this headline -- dozens killed in the street by street battle for sanaa and the article talks about the worsening situation there. yemen is on the brink of financial ruin with about a third of its 23 million people facing chronic hunger. it is running out of oil and water. one issue many you can read, all those articles in full at facebook.com. we turn to europe where worries are growing over exactly what is safe to eat after russia said it was banning fresh vegetables from the eu to keep out a deadly e. coli infection. it's killed 15 people in germany and one in sweden, according to local media reports. german scientists said at first they thought it came from cucumbers shipped in from spain. now they admit, that was a mistake, but haven't pinned down the real source of this bacteria. russian officials have ordered stores to take eu vegetables off the shelves. according to reuters news agency, the eu has attached the import ban calling it disproportionate. we're joining by matthew chance in moscow and we understand the consumer protection agency, the head of the consumer protection agency in russia is actually attacking the eu health standards when it comes -- they're saying these health standards russia has been asked to follow and now they're saying that's not even good enough. >> reporter: certainly russia often gets compared to the you' european union. the chief consumer affairs doctor here in russia has issued that attack against the european health certificates and standards in the european union. he said that this incident with the e. coli infections shows that europe's lauded health regulation, one russia is urged to adopt, does not work. you know, it's not just politics, of course. there is a genuine concern in russia about this outbreak of e. coli and they made it clear because the outbreak has been going on for more than a month and because the source has not been located in the european union, that the decision has been taken to not just ban the import of all fresh vegetables from eu countries to russia but also to seize any vegetables that have been imported from the european union into russia so far. >> matthew, how much of goods -- i guess, fresh vegetables from the eu is actually consumed by russian or imported by russia? >> reporter: well, quite a lot, particularly in the european part of russia. though, i have to say countrywide, russia gets the majority of fresh vegetables from countries like china, from countries like turkey as well. it's much more significant, though, in terms of what the european do because some 25% of all the fresh produce exported from the european union goes to the russian markets. so, it's a major economic blow for european farmers who depend very much for at least a quarter of their exports on russia where their fruit and vegetables are now banned. >> matthew chance, thank you, reporting from moscow. you're watching "world one" live from london. coming up, a string of deadly tornadoes strike the u.s. state of massachusetts. we're going to bring you the very latest on the rescue operation.
