People walk towards the grave of the late Iranian Revolutionary Guard Gen. Qassem Soleimani in the city of Kerman about 510 miles (820 kms) southeast of the capital Tehran, Iran, Thursday, Jan. 4, 2024. Investigators believe suicide bombers likely carried out an attack on a commemoration for an Iranian general slain in a 2020 U.S. drone strike, state media reported Thursday, as Iran grappled with its worst mass-casualty attack in decades and as the wider Mideast remains on edge.
