Oh Crap

If reports from the Ukrainian government are true, and I'm not big on the idea of trusting them, then they just shelled a Russian aid convoy:

Ukraine claims it has destroyed Russian military vehicles in the country's east, a day after a column was spotted moving across the border.

Ukraine's president, Petro Poroshenko, told David Cameron by phone that his country's armed forces had destroyed part of an armed convoy that the Guardian saw moving through a gap in a border fence on Thursday night.

There was no immediate proof, and it was impossible to establish if the Ukrainians had targeted the same convoy seen by the Guardian. The Russians categorically denied that any of their troops were even in Ukraine. But the claim marks a new escalation in the six-month confrontation over Ukraine and if verified would amount to the first confirmed military engagement between the two adversaries since the crisis began in the spring.

"The president informed [Cameron] that the information was trustworthy because the majority of those machines [Russian military vehicles] had been eliminated by the Ukrainian artillery at night," a statement from Poroshenko's office read.

Russia is denying this, but if this is true, or worse, they shelled an aid convoy in the dead of night, the Russians have arranged one with the Red Cross, things are going to go pear shaped quickly.
