A doctor treats a soldier at a hospital in Sanaa after he was injured when a Yemeni soldier packing powerful explosives under his uniform blew himself up in the middle of an army battalion in Sanaa on May 21, 2012, killing 96 troops and wounding around 300, a military official and medics said. The suicide attack was the deadliest in the country’s capital since newly-elected President Abdrabuh Mansur Hadi pledged to oust Al-Qaeda militants from Yemen’s mostly lawless and restive southern and eastern provinces.
