KIEV/DONETSK Ukraine (Reuters) - Ukrainian President Petro Poroshenko vowed to "find and destroy" pro-Russian rebels who killed 23 servicemen and wounded nearly 100 in a missile attack on Friday.

Poroshenko issued his angry statement following an emergency meeting of his security chiefs called in response to the early morning strike by Russian-made Grad missiles on an army motorised brigade near the border with Russia.
