Activists say air raids and the subsequent crash of a Syrian warplane in a residential area in the northwestern town of Ariha has killed and wounded dozens of people.

The Britain-based Syrian Observatory for Human Rights and the Local Coordination Committees had no immediate specific death toll for the violence Monday.

The town of Ariha, once a government stronghold, was captured by opposition fighters and Islamic militants in May.

The Observatory and the Local Coordination Committees said that at the time of the crash, the town was under attack by the air force of embattled Syrian President Bashar Assad.

Syria's civil war began in March 2011. The United Nations says the war has killed more than 220,000 people and wounded at least 1 million.
