The U.N. secretary-general and the U.S. government condemned a deadly attack on the Camp of 'Liberty' in Western Baghdad early on Saturday and urged Iraqi authorities to carry out a full investigation. "(Ban Ki-moon) strongly condemns the mortar attack today on Camp Liberty, the temporary transit facility near Baghdad for former residents of Camp Ashraf," the secretary-general's press office said in a statement quoted by Reuters. At least five people were killed and more than 25 wounded in the rocket attack, police sources said. "The Secretary-General calls on the Government of Iraq, which is responsible for the safety and security of residents of both Camp Liberty and Camp Ashraf, to promptly and fully investigate the incident and bring perpetrators to justice," it said. The U.S. State Department condemned "in the strongest terms the vicious and senseless terrorist attack." "We understand the Government of Iraq has undertaken to promptly investigate the attack," State Department spokeswoman Victoria Nuland said in a statement. "We call on it to earnestly and fully carry out that investigation and to take all appropriate measures to enhance the security of the camp consistent with its commitment and obligation to the safety and security of the camp's residents. "The terrorists responsible for this attack must be brought to justice," the U.S. statement added.
