A British security firm said today that four employees were killed and 15 others injured in an attack in Baghdad's Green Zone.

Tim J. O'Brien, spokesman for the London-based Global Risk Strategies, confirmed that four company employees were killed Thursday and another 15 had various injuries. O'Brien declined to say what type of attack had occurred.

"There was an incident yesterday. We lost four people and had 12 to 15 who were injured," he said. "We can't confirm what this incident actually was until we go through internal investigations."

Multiple explosions were heard Thursday and black smoke was seen rising from the fortified Green Zone, which houses the U.S. and Iraqi leadership. The protected area lies on the western bank of the Tigris River.

O'Brien refused to give out identities of those injured, saying their next of kin needed to be notified. However, none of those killed were American, he said.

Global Risk Strategies is a London-based firm that provides security in countries including Iraq and Afghanistan.
