乌克兰总统：俄罗斯可能发动新的袭击

Ukrainian President Petro Poroshenko has warned that there are 9,000 Russian troops in the rebel-controlled area of eastern Ukraine and warned the country must be on alert for a large-scale attack.

Mr. Poroshenko made the comment to parliament Thursday, saying there exists a "colossal" threat of major new attacks.

He spoke a day after a major battle flared outside a main separatist stronghold in eastern Ukraine.

Firefighters scrambled to put out a fire at an open air market near Donetsk following a suspected rocket attack.

The Kremlin insists it has no direct role in the crisis, and has repeatedly denied supporting the rebellion with arms and fighters.

The truce signed by Russia, Ukraine, France and Germany in February required both sides to withdraw heavy weapons from the line of contact.

But international observers say those provisions have been routinely violated.

波罗申科星期四在议会讲话时说，乌克兰面临新的重大攻击的"巨大威胁"。

在此前一天，乌克兰东部分离分子的主要据点顿涅斯克附近爆发战斗。

顿涅斯克附近的一家露天市场疑遭火箭炮弹袭击，消防人员紧急扑灭火灾。

俄罗斯当局一直否认直接卷入乌克兰危机，并一再否认向乌克兰反政府武装提供武器和战斗人员。

俄罗斯、乌克兰、法国和德国今年二月签署的停火协议要求冲突双方从接触地区撤走重型武器。但是国际观察人员说，这些规定经常被违反。
