"Hamas mourns commander Soleimani and the Iraqi martyrs who were killed today by a US airstrike," said Hamas in a statement on Friday.
The resistance group expressed its condolences to the Iraqi people for those killed in the airstrike.
Hamas also expressed condolences to the Iranian people on the "assassination of General Soleimani who provided various support to the Palestinian resistance."
"We condemn such US policy of insolence and the continued US crimes which aim at creating chaos in the region for the benefit of the Zionist enemy," the group added.
The statement also held the US responsible for the repercussions of the assassination in the entire region.
Major General Soleimani, the deputy head of Iraq’s Hashd al-Shaabi (PMU), and a number of their entourage were killed in a strike by American drones near Baghdad International Airport in the early hours of Friday.
The White House and the Pentagon confirmed the assassination of General Soleimani in Iraq, saying the attack was carried out at the direction of US President Donald Trump.
