				A senior official in Kiev has accused Russia of invading Ukraine after Russian humanitarian aid lorries crossed the border without permission. 
 
Security chief Valentyn Nalyvaychenko said it was a "direct invasion" but no force would be used against the convoy.  
 
Russia began sending in its lorries, stranded at the border for more than a week, after formally accusing Ukraine of unreasonable obstruction.

 So Russia warns a sovereign nation against taking action against a foreign convoy which has entered its territory without permission.  I wonder if they'd accept that sort of threat if the situation were reversed...
