BBC: Ukraine's Poroshenko warns of 'full-scale' Russia invasion

President Petro Poroshenko has told MPs the military must prepare to defend against a possible "full-scale invasion" from Russia, amid a surge of violence in eastern Ukraine.

Russia has denied that its military is involved in Ukraine, but Mr Poroshenko said 9,000 of its troops were deployed.

Clashes involving tanks took place in two areas west of Donetsk on Wednesday.

There was a "colossal threat" that large-scale fighting would resume, the president told parliament in Kiev.

The outbreak of violence, in the government-held towns of Maryinka and Krasnohorivka, was among the worst in eastern Ukraine since a ceasefire was signed in Minsk in February.

WNU Editor: There are 50,000 Ukrainian soldiers in eastern Ukraine, and apparently they are now on the move .... VOA Witnesses Troop Movements in E. Ukraine (VOA). If true .... expect the war to resume in the next few days (if not sooner).
