Iraq base housing US troops hit in second rocket attack this week, officials say

A barrage of rockets hit a base housing US and other coalition troops north of Baghdad, Iraqi security officials said on Saturday, just days after a similar attack killed three servicemen, including two Americans.

The officials said over a dozen rockets landed inside Camp Taji, some striking the coalition headquarters while other fell on a runway used by Iraqi forces.

Camp Taji was also the site of Wednesday's attack, the deadliest to target US troops in Iraq since a later December rocket attack on an Iraqi base. 

In retaliation for Wednesday's rocket fire, the US launched a series of airstrikes on militia bases across Iraq's south, killing five Iraqi security forces and a civilian.

There was no immediate word on casualties on Saturday at Camp Taji, according to the officials, who spoke on condition of anonymity in line with regulations. US security officials also confirmed the strikes to AFP but made no mention of casualties.
