BEIRUT (AP) — Syrian opposition activists and a war monitor say five people have been killed in airstrikes on a town in the country's northwest as the government keeps up its deadly air campaign against the rebel-controlled region.

The Syrian Observatory for Human Rights, a war monitor, said two of the five civilians killed on Sunday were members of the same family.

The opposition-affiliated first responders known as the White Helmets said 21 people were wounded the town of Ariha.

Activists said an airstrike hit a busy market there a day earlier, killing 11 people.

The town has been particularly targeted over the past week, as the government looks to regain momentum in its stalled offensive against Idlib province, which began in late April.
