Washington (CNN) The US-led military coalition fighting ISIS announced Sunday that it's temporarily stopping its counter-ISIS missions in order to focus on protecting Iraqi bases and coalition forces there from Iranian-backed militias.

Citing the recent attacks by the Kataib Hezbollah militia, which have resulted in the deaths of a US civilian contractor and Iraqi security forces, the coalition said: "We are now fully committed to protecting the Iraqi bases that host Coalition troops."

"This has limited our capacity to conduct training with partners and to support their operations against Daesh and we have therefore paused these activities, subject to continuous review," the coalition said in a statement, using the alternative name Daesh for ISIS.

The change in priorities adds to a growing list of maneuvers by the US in response to increasing tensions in the region. The US is currently bracing for potential retaliatory actions by Iran and militias backed by the country in response to a US attack in Iraq last week that killed Iranian military commander Qasem Soleimani and several others.

On Sunday, the military adviser to Iran's Supreme Leader said his country's response to the killing of Soleimani will certainly be a military response "against military sites."
