Arab coalition spokesperson Col. Turki Al-Maliki said the militants had started carrying out simultaneous attacks as part of their terrorist tactics.
Similar tactics were used in Aden on Thursday, Aug. 1 when a military parade was targeted killing 11 people, with the assistance of a Daesh affiliate.
Al-Maliki said attacks which target civilians are a breach of international humanitarian law and are considered a war crime and he said the coalition would continue fighting the Houthis, which he said was legal under international law.
