BAGHDAD: Rockets were fired from northern Iraq at a US-led coalition military base in Syria late Sunday, according to Iraqi security forces.
The Iraqi forces in response, launched a major search operation in Nineveh province in northern Iraq and found the vehicle used in the attack, a statement said.
This is the first such attack against the US-led coalition forces in Syria in several weeks.
The development comes days after Israel reportedly responded to an Iranian attack with a drone strike on Tehran, amid heightened tensions due to the Gaza war.
The statement from the Iraqi security forces blamed the outlaw elements for targeting a base of the international coalition with rockets in the Syrian territory, at around 9:50 p.m. (1850 GMT).
Rami Abdel Rahman, director of the Syrian Observatory for Human Rights war monitor, said many rockets were fired from Iraqi territory at the Kharab Al-Jir base.
He said the Islamic Resistance in Iraq, was behind the attack.
The group has claimed responsibility for most of the attacks on US forces between mid-October and early February.
After a series of rocket attacks and drone strikes by armed factions against US soldiers deployed in the Middle East in the winter, there had been calm for several weeks.
The United States has around 2,500 soldiers deployed in Iraq and nearly 900 across the border in Syria as part of an international coalition founded in 2014 to fight the Daesh group (IS).
