BEIRUT — Syrian activists say an Islamic State suicide bomber has targeted a predominantly Kurdish town in northeastern Syria, killing at least 11 people.

The Britain-based Syrian Observatory for Human Rights says Wednesday's explosion happened outside a local Kurdish police station in the town of Qamishli. It also says more than 40 people were wounded.

Syria's state news agency SANA reported the explosion, saying it killed 13 and wounded about 50.

The Islamic State group has been fighting Kurdish fighters in Syria since last year and the extremists have carried out dozens of suicide attacks against the Kurds. The Kurdish fighters, aided by U.S.-led airstrikes, have also captured significant territory from IS in northern Syria.
