Ukraine'destroys' Russian military vehicles

Ukraine says it has partially destroyed an armoured column crossing
from Russia, as a controversial Russian aid convoy still waits at the
border.

Nato said the column was a military "incursion", prompting the UK to
summon Russia's envoy to explain.

Russia's defence ministry denied any such column had entered Ukraine.

Meanwhile Ukrainian border guards have arrived to inspect Russia's aid
convoy, which was sent to help eastern Ukraine cities held by
pro-Russian rebels.

Berlin meeting

The alleged incursion by Russian military vehicles into Ukraine was
witnessed on Thursday by two UK newspaper reporters.

The BBC's Daniel Sandford in Moscow says the crossing was a reminder
of the extent to which the Kremlin has been backing the rebellion in
eastern Ukraine.

It is not known whether the troops moving with the military column
were Russian or pro-Russian separatis.

Ukraine's President Petro Poroshenko said on his presidential
websitethat he had discussed the incident with UK Prime Minister David
Cameron.

Mr Poroshenko said the information was "trustworthy and confirmed
because the majority of the machines had been eliminated by the
Ukrainian artillery at night".

Andriy Lysenko, a spokesman for the Ukrainian military, added:
"Appropriate actions were undertaken and a part of it no longer
exists."

The UK Foreign Office summoned Russian Ambassador Alexander Yakovenko
"to clarify reports of Russian military incursion".

EU foreign ministers warned they were ready to consider further
sanctions 'in light of the evolution of the situation on the ground'

Russia's defence ministry said the incursion reports were "some kind
of fantasy".

It said: "There was no Russian military column that crossed the
Russian-Ukrainian border either at night or during the day."

Meanwhile Ukraine's Foreign Minister Pavlo Klimkin sent out a tweet
saying he would be meeting Russia's Sergei Lavrov in Berlin on Sunday,
along with their French and German counterparts, adding: "We need to
talk."

Nato Secretary General Anders Fogh Rasmussen said: "We see a
continuous flow of weapons and fighters from Russia into eastern
Ukraine, and it is a clear demonstration of continued Russian
involvement in [its] destabilisation."
