More details of Russia's military exercises at Ukraine's doorstep.
From our newsroom, summarizing what we know at this point about the hundreds of Ukrainian troops who crossed the border into Russia overnight. Still conflicting information on the cause and their intentions:
Russian news agencies report that more than 400 Ukrainian soldiers crossed into Russia overnight, allegedly to avoid fighting with pro-Russian rebels in eastern Ukraine.
The Ukrainian military confirmed that an undisclosed number of troops had crossed into Russia but it denied Russian media reports the soldiers were seeking refugee status.
The Russian media reports quoted a senior security official as saying a "humanitarian corridor was opened" for 438 Ukrainian soldiers who asked permission to enter Russia.
The soldiers were reportedly surrounded by the rebels after they ran out of ammunition.
The reports said 180 of the troops had since been returned to Ukraine.

Soldiers in eastern Ukraine explained to our Ukrainian Service how they converted a Russian-made army truck into a bullet-proof armored vehicle to help them battle separatists. They used thick metal sheets to reinforce the driver's cab and the sides of the Ural off-road truck, which also carries an automatic grenade launcher.
The fighting comes to Donetsk in earnest:
