At least five missiles struck an Iraqi military base hosting US troops in the country’s western desert on Monday, two Iraqi security officials said.
Officials said Grad missiles struck inside the Ain al-Assad base in Iraq’s western Anbar province and caused minor damage but no casualties.
Officials said the missiles were only a few meters (yards) away from where the US military was stationed. The officials spoke on condition of anonymity because they were not authorized to brief the media.
The perpetrators were not immediately known, but the US has previously accused Iran-backed Iraqi militia groups of targeting the US presence in Iraq, including the US embassy in Baghdad.
Attacks were once frequent, but have lessened in recent months.
In March, Iran attacked Iraq’s northern city of Irbil with a dozen ballistic missiles, claiming it was targeting Israeli spy stations. Iraq later said that an investigation found no Israeli presence in the areas. The attack was also seen as a warning to the US, a staunch ally of Israel.
The US-led coalition has recently ended its combat missions in Iraq, but continues to play an advisory role to Iraqi forces in the fight against the Islamic State extremist group.
