Attacks targeting exiled Yemeni officials and Saudi-led troops fighting in the country’s civil war have killed at least 15 people in the port city of Aden, authorities said.
A new Islamic State affiliate claimed responsibility for the assault, which officials previously blamed on Yemen’s Shiite rebels.
The addition of IS into Yemen’s months-long war would only add to the chaos on the ground in the Arab world’s poorest country.
Previously, the Sunni extremists largely targeted Shiite mosques in Yemen as a myriad of forces fought over the removal of internationally recognised president Abed Rabbo Mansour Hadi by the Shiite rebels known as Houthis.
The attack on the Al Qasr Hotel & Resort, a large compound that Yemeni officials use as a headquarters, happened early on Tuesday morning.
A blast struck the front of the 239-room hotel along the Arabian Sea, west of the port city’s centre, sending thick black smoke rising over it for hours as sirens wailed.
Two other attacks followed on locations used by troops from the United Arab Emirates, which has the most overt presence among coalition forces inside Yemen.
The official Saudi Press Agency blamed the Houthis for the attack, saying the rebels fired Russian-designed Katyusha rockets.
Those rockets are part of the Yemeni military stockpile that the Houthis, as well as al Qaida’s local branch in the country, have seized amid the war’s chaos.
But by Tuesday afternoon, the new IS affiliate in Aden claimed the attacks in a message circulated by militant sympathisers online.
