The US-led coalition conducted 12 air strikes against Islamic State militants in Syria yesterday and 10 strikes Iraq, the US military said in a statement.
In Iraq, the strikes hit near the strategic northern Iraqi town of Sinjar as well as near Asad, Tal Afar, Ramdi, Mosul and Falluja, the Combined Joint Task Force said. They destroyed six units of Islamic State fighters as well as a weapons factory, numerous buildings and several vehicles, it said.
"These engagements were in support of the 7th Iraqi Army, local police and tribal fighters engaged in fighting with ISIL forces in the vicinity of Dulab," the statement said.
On Sunday, Kurdish and Yazidi fighters battled to take the Sinjar back from Islamic State after breaking a months-long siege of the mountain above it. Seizing the town would restore the majority of territory Iraq's Kurds lost in Islamic State's surprise offensive in August.
In Syria, the dozen strikes centered around the border town of Kobani as well as Aleppo, Hasaka and Raqqa, destroying various fighting positions, vehicles and a group of fighters, the statement said.
At least four Syrian school children were killed and 10 wounded yesterday when a regime air strike hit their bus in the northwest of the country, a monitor said.
The Syrian Observatory for Human Rights said most of those wounded and killed when the Syrian air force hit a school bus near the village of Jubass in Idlib province were under the age of 10, reports AFP.

"The toll could go rise as there are serious injuries," said the monitor, which has a wide network of sources on the ground across Syria.
Idlib is largely in the hands of Syria's Al-Qaeda franchise, Al-Nusra Front, which in recent weeks has fended off advances by rival rebel groups and now holds two strategic military bases in the province.
Syria's air force is a significant tool in the arsenal of President Bashar al-Assad, whose forces have fought a devastating conflict against insurgents since 2011.
