It was the 23rd such attack since late October on installations across
Iraq where
American troops and
diplomats are based, with the latest rounds growing deadlier.
At least 33 rockets hit Iraqi air defence units at the Taji air base on Saturday, the country's military said, in one of the largest such volleys yet.
"The initial toll is two wounded Iraqi Air Defence personnel who are in very critical condition," said Tahsin al-Khafaji, spokesman for Iraq's Joint Operations Command.
