Four Katyusha rockets were fired at the Ain al-Assad base in Iraq, where troops of the US-led international anti-jihadist coalition are stationed, two security sources told Reuters news agency. As of this stage, no casualties or damage have been reported, they said.

The sources clarified that the two rockets fell inside the base and the remaining two in its perimeter.

A spokesman for the coalition did not immediately respond when asked for comment.

The attack was launched two days after Iraqi and US officials held talks in Washington on phasing out the mission of the coalition, which was formed to counter the Islamic State (IS) group, in Iraqi territory.

No major announcement was made after the talks. Officials in Washington and Baghdad, however, say they expect the start of the coalition withdrawal process to be formalized within weeks.

Iraqi political factions and paramilitary organizations are pressuring the country’s government to push for the rapid withdrawal of foreign forces, demanding the roughly 2,500 members of the US military — the former occupation force — leave.

The US and Iraqi governments say they want to sign a bilateral security agreement, within the boundaries of which some US military personnel will remain, in an advisory role.

US forces invaded Iraq in 2003, ousted then-leader Saddam Hussein and imposed an occupation, then withdrew in 2011 before returning in 2014 to tackle IS.

Paramilitary groups close to Iran have targeted US forces dozens of times on Iraqi and Syrian soil since war broke out between Israel and Hamas in the Gaza Strip on October 7. However, the attacks have decreased since February.
