Ukrainian law enforcement units have assumed a large-scale offensive on Lugansk, the militia said.
"Fierce fighting is underway on the limits of Lugansk. The situation is not clear yet, but reports that the enemy deployed two compact armored groups of about 70 tanks in all, are being confirmed. Immediate unverified reports indicate that a special police task force was dropped on the city from helicopters," Vladislav Brig, spokesman for the Donbass militia, wrote on Facebook.
The offensive on Lugansk was launched from the southern and western directions, he said, Interfax reports.
