Nine rockets hit Iraq base housing US troops: security sources

• At least nine rockets slammed into an Iraqi airbase in the country's west early Wednesday.
• The attack on the Ain al-Asad airbase came after pro-Tehran factions in Iraq.

The attack on the Ain al-Asad airbase came after pro-Tehran factions in Iraq had vowed to join forces to "respond" to an American drone strike that killed Iranian general Qasem Soleimani and Iraqi top commander Abu Mahdi al-Muhandis in Baghdad last week.
