Kataib Hezbollah spokesman said the suspension was conditional on the Iraqi government presenting the timetable for the withdrawal of US troops.
“It includes all the factions of the [anti-US] resistance, including those targeting US forces, ”he told Reuters news agency.
Mohi said the Iraqi government must implement a parliamentary resolution in January that called for the withdrawal of foreign troops from Iraq.
The parliament’s decision came after a U.S. drone strike at Baghdad airport on January 3 killed Iranian General Qassem Soleimani and Iraqi Shiite paramilitary leader Abu Mahdi al-Muhandis, raising fears of a full-scale confrontation between Iran and the United States on Iraqi soil.
Mohi said there was no deadline for the government to implement the decision, but warned, “If America insists on staying and does not respect parliament’s decision, the factions will use all weapons at their disposal.
He said the Katyusha rocket fire at US forces and diplomatic complexes was simply “a message that you are not welcome in the country” and that worse attacks could follow.
US officials blame Kataib Hezbollah for dozens of rocket attacks on US facilities in Iraq.
Kataib Hezbollah denies having executed them. Smaller and hitherto unknown groups have claimed responsibility for some of the attacks. Iraqi security sources believe these groups are linked to Kataib Hezbollah and other larger groups aligned with Iran.
