KIEV (Reuters) - Ukraine said on Sunday that a convoy of 106 vehicles had entered its eastern territory from Russia without Kiev's permission and accused Moscow of once again using humanitarian aid shipments to send weapons and ammunition to separatist rebels.

In the separatist-held city of Donetsk, fighting intensified at the local airport, a Reuters witness said. There has been continued shelling from both government forces and the rebels, even after a peace deal signed on Sept. 5.
