Three rockets targeted the Arbil airport in northern Iraq’s Kurdistan region, one of which hit a military complex where US-led coalition troops are based,AFP reported

The two others hit residential areas near the airport,killing  a foreign contractor and wounding 5 others.

The indirect fire represents the first time US military or diplomatic installations have been targeted in Iraq in nearly two months.

Both American and Iraqi officials have blamed hardline armed groups, including the pro-Iran faction Kataeb Hezbollah and Asaib Ahl al-Haq.

These groups are vehemently opposed to the US-led coalition, which has been based in Iraq since 2014 to help local forces fight back the Islamic State group.

With IS largely defeated, the coalition has drawn down to under 3,500 forces in total, 2,500 of which are US troops.

In October, the US threatened to close its embassy there if the rocket attacks did not stop, so hardline groups agreed to an indefinite truce.

There have been several violations since then, the most recent of which, prior to Monday night, was a volley of rockets targeting the US embassy on December 20.
