Syrian rebels on Tuesday have killed 7 YPG militants in surprise attack in rural Aleppo province, local reporter said.
The rebel factions launched a surprise attack on the bastion of the powerful Kurdish militia at the interface of Tel Refaat town, killing seven.
In its turn, the regime army and allied forces captured Maskaneh, the last major town held by Islamic State in eastern Aleppo on Sunday, state media and a war monitoring group said.
State-run news agency SANA said army units made strategic gains in the rural east of the province.
In its turn, regime forces entered the town of Maskaneh on Sunday after weeks of heavy fighting.
The advance brings Russian-backed regime forces to the border of Raqqa province, which is largely under the control of U.S.-backed militias also fighting Islamic State.
A Syrian military source said the army "restored security and stability" to Maskaneh and nearby positions. Troops also regained large generators that power a main water pumping station, the source said. The army had retaken the water plant from Islamic State in March
