Authorities in the Yemeni city of Taiz and surrounding areas have stepped up security measures around the offices of international organizations and have approved a ban on carrying weapons. The new measures were introduced days after a World Food Program (WFP) staff member was shot and killed by unknown gunmen in Turbah in southern Taiz. Official sources revealed that Taiz Governor Nabil Shamsan and members of the security committee met in the southern Taiz countryside and approved the tightened measures and weapons ban.
