BAGHDAD - The Iraqi National Intelligence Service (INIS) said Saturday that its headquarters in Baghdad was targeted by a "terrorist attack," resulting in the death of an officer.

An INIS statement said the attack occurred at about 10:00 am local time (0700 GMT) and was carried out by "outlawed elements," noting that it aims to deter the agency from performing its duties.

It said that the "terrorist acts" only strengthen its resolve to pursue the perpetrators until they are apprehended and brought to justice.

Meanwhile, a source from the Iraqi Interior Ministry told Xinhua on condition of anonymity that an unidentified booby-trapped drone struck the intelligence headquarters, killing an officer and sparking a fire.
