At least four people were killed and eight others wounded Wednesday in a fresh mortar attack in Syria's northern province of Aleppo, the official media said.

The mortars slammed the Mokambo area in Aleppo, causing also property loss, said the report, spelling no further details.

The state media accused "terrorists" of being behind such attacks across Syria.

Aleppo, once called the economic hub of Syria, has emerged as a main battleground between the rebels and the Syrian troops.

The nearly 3-year-old crisis in Syria has claimed the lives of more than 100,000 people and displaced millions of others.
