A pair of rockets hit a residential district near the Iraqi capital’s high-security Green Zone late on Tuesday, a security source said, in the second such attack of the day.

The projectiles hit an apartment building and wounded three people there, the source said. No diplomatic missions in the Green Zone were affected, diplomatic sources said.

Just before dawn Tuesday, rockets hit a military base at Besmaya, where US-led coalition troops and NATO forces are deployed alongside Iraqi troops.
