The US-led coalition allegedly formed in a bid to “combat terrorism” in Iraq and Syria, launched new airstrikes on Thursday overnight, hitting oil facilities for a second day.

The Syrian Observatory for Human Rights reported new air strikes in eastern Deir Ezzor province and northeastern Hasakeh province, both of which were targeted a day earlier by the coalition.

The Britain-based group said at least two areas in Deir Ezzor were struck, with the strikes appearing to target oil facilities.

Additional strikes hit an area in Hasakeh, where the target was not immediately clear, the group's director Rami Abdel Rahman said.

Earlier on Wednesday overnight, five civilians were killed, including a child, as the US-led strikes hit the Hasakeh province. 14 militants were killed in other strikes in Deir Ezzor.

The strikes came on a fourth night of bombing by the coalition Washington has assembled to tackle the Takfiri group operating in Iraq and Syria, ISIL.

The strikes have killed at least 140 militants and 13 civilians so far, according to the Observatory, though Washington has yet to acknowledge any civilian casualties.
