Ukraine prepares missile test near Crimea, angering Russia

KIEV (Reuters) - Ukraine was due to start two days of missile tests on Thursday - a move that has angered Russia, prompting it to put its air defence forces on high alert on the annexed Crimea peninsula.

The disagreement marks a fresh escalation in tensions between the one-time allies, whose relations collapsed in 2014 after Russia seized Crimea and backed pro-Russian separatists fighting in eastern Ukraine.
