BBC News with Jonathan Izard. Ukraine's interim interior minister says shooting has broken out in the eastern town of Kramatorsk. Arsen Avakov said pro-Russian demonstrators tried to storm a government building. In the eastern city of Sloviansk unidentified gunmen seized police and state security buildings and raised the Russian flag. Our correspondent in Sloviansk, David Stern, says no one knows who carried out the assault there. The gunmen seemed to be extremely well organised. We saw these, the barricades already have been erected within minutes of our arrival in the town of Sloviansk. We also saw numerous checkpoints and road blocks on the road going from Donetsk, on a couple of roads going from Donetsk to Sloviansk. And the gunmen all seemed to be very well equipped. They were wearing these unmarked green uniforms, which, it has to be said, we also saw in Crimea._______________________________________ 乔纳森?艾扎德为您带来BBC新闻.乌克兰临时内政部长称东部城镇克拉马托尔斯克爆发枪战.阿尔森?埃瓦科夫说,亲俄示威者试图抢占一栋政府大楼.而在东部另一城市斯拉维扬斯克,不明身份的武装分子占领了警察局和国家安全部门大楼,并升起了俄罗斯国旗.我们的记者大卫?斯特恩在斯拉维扬斯克,他表示没有人知道这次袭击的策划者是谁. 那伙武装分子显得非常有组织.在我们到达斯拉维扬斯克几分钟之内,就看到路障被设立起来了.我们也看到在通往顿涅茨克的路上设有许多检查点和路障,在几条连接顿涅茨克和斯拉维扬斯克的道路上,也有这种情况.那些武装分子似乎都进行了全身武装,他们穿着没有标识的绿色军服,而我们不得不说,这种绿色军服在克里米亚也出现过._____________________________________
