Ukrainian government forces have launched an anti-terror operation to retake the rebel stronghold of Slavyansk, with two troops reported dead after separatists used grenade launchers against military helicopters surrounding the city.
Gunfire and blasts were heard early this morning around the eastern city in Ukraine that has become the focus of an armed pro-Russian insurgency, whose leaders claimed that government troops had began a military assault in an attempt to retake control.
Ukrainian officials said Slavuyansk was "tightly surrounded" and called on separatist leaders to release hostages and surrender.
Interior Minister Arsen Avakov said the offensive was answered with heavy artillery, with the rebels using grenade and portable anti-aircraft missile launchers to bring down planes.
"As a result of the shooting, two troops from the Ukrainian army were killed," Ukraine's Interior Ministry said in a statement.

Russian President Vladimir Putin's spokesperson accused Kiev of launching a "punitive operation" in south-east Ukraine, destroying the final hope of keeping alive the Geneva agreement designed to defuse the crisis, Russian news agencies reported.
Vyacheslav Ponomarev, the insurgency-appointed mayor of Slavyansk, said self-defence forces had shot down two helicopters, killing one pilot and capturing the other. Details of these claims could not be independently verified.
Describing the operation as "the active phase of the anti-terrorist operation", Mr Avakov said its goals were simple - "free the hostages, lay down their arms and free administrative buildings, and restore the normal functioning of the town's administration".
