US-led coalition air raids targeted towns and villages in northern and eastern Syria controlled by Daesh militants, ABC News quoted activists as saying on Monday.
The Britain-based Syrian Observatory for Human Rights said coalition forces hit Daesh facilities overnight in Aleppo, Raqqa, Hassakeh and Deir el-Zour provinces. It said there were casualties, including civilians, but did not have exact figures.
One of the strikes hit a grain silo in the extremist-held town of Manbij in Aleppo province, setting it ablaze.
In Deir el-Zour province, a strike overnight attributed to the coalition hit the entrance to the Conoco gas plant, Syria's largest, according to the Observatory. It said the facility itself was not damaged.
More raids Monday morning struck the town of Tel Abyad on the Syria-Turkey border, according to a resident on the Turkish side on the frontier.
The raids hit an abandoned military base and an empty school, sending pillars of smoke and dust into the air.
