Suicide attackers set off two car bombs in Yemen's Red Sea port city of Hodeida on Thursday, killing themselves and causing a number of other casualties, sources in the Shi'ite Muslim Houthi movement told Reuters. Three other suspected bombers were killed by members of so-called citizen committee security patrols before they were able to attack, the sources said. 'The bombs rocked the city. They were targeting a building that belonged to Houthi movement officials,' said a resident.
