ADEN, Yemen (AP) -- Yemeni military investigators say 12 militants, mostly Saudi nationals, were responsible for a brazen attack on the Defense Ministry's complex in the capital.
The committee led by Yemen's Chief of Staff Gen. Ahmed al-Ashwal put out a report Friday that set the death toll at 56, with another 215 wounded.
It described Thursday's attack as a two-stage operation, in which attackers disguised in military uniform drove a car packed with explosives into the complex, blew it up, then split into two groups. One swept through a military hospital while the second group attacked a laboratory. Both killed everyone they found.
A copy of the report was obtained by The Associated Press.
Officials earlier said 11 militants were killed. It was not clear if the 12th attacker was captured or escaped.
