Ukraine’s warns of 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 the worst since a ceasefire was signed in Minsk in February.

Government troops fired shells at rebel-held areas on the outskirts of Donetsk.

Ukraine said it had lost five soldiers in the past 24 hours, while the rebels said 15 people including civilians had been killed.

The separatists denied Ukrainian claims that they launched a major offensive in violation of a truce.

Russian Foreign Minister Sergei Lavrov accused the authorities in Kiev of jeopardising the Minsk agreement, by placing it "under the constant threat of disruption" and by refusing to engage in direct dialogue with separatist leaders.

The Kremlin has consistently denied sending serving soldiers across the border, although it has acknowledged that "volunteers" have joined the rebels.

In his annual address to parliament, Mr Poroshenko warned of a "colossal threat" from the rising violence.

"Ukraine's military should be ready for a new offensive by the enemy, as well as as full-scale invasion along the entire border with the Russian Federation," he said. "We must be really prepared for this."

More than 6,400 people have been killed in eastern Ukraine since the conflict began in April 2014 when rebels seized large parts of the two eastern regions, following Russia's annexation of the Crimea peninsula.

Mr Poroshenko said Ukraine had 50,000 troops in the east who were able to defend the country.

What he described as the Kremlin's "plan to sow separatism in south-eastern Ukraine" had failed, he added, and only persisted in areas of the Donetsk and Luhansk regions because of "Russian bayonets".
