WASHINGTON (AFP) - The suspect who opened fire at police outside the Pentagon died after being shot by officers, Pentagon police said Friday, adding that the American had no connection to terrorism. There is no indication at this point that there are any domestic or international terrorist connections at all, chief Richard Keevill of the Pentagon Force Protection Agency told reporters about Thursdays shootout in front of shocked onlookers. The suspect, identified as 36-year-old John Patrick Bedell of California, passed away after being shot in the head by officers, two of whom were wounded in the assault but were expected to recover, Keevill said. Bedell pulled a gun from his pocket and opened fire outside the Pentagons metro entrance, injuring two police officers before he was shot and seriously wounded. The shooting occurred during the crowded evening rush hour outside the busy subway station which is just outside the large Department of Defence building, triggering a temporary security lockdown at the US military headquarters. The suspect appeared to be pretty calm as he approached the entrance, Keevill told reporters. As the officers started to ask him for his pass... he drew a weapon from his pocket and started shooting, Keevill said. He did not say anything. Police returned fire and the suspected shooter was critically wounded, Keevill said. The injuries to the two police officers appeared to be grazing wounds and not life threatening, he said. The three were taken to nearby George Washington University hospital for treatment while the motive of the suspected gunman remained unclear. The Pentagon later lifted the security lockdown and reopened its entrances after deciding that the danger had passed, although the Washington transit authority said Metros Pentagon station would be closed for the Friday morning rush hour to allow an FBI investigation to proceed. Metro authorities also said officials were investigating reports of suspicious packages outside the station but defence officials could not confirm the report. The shooting occurred at 6:40 pm (2340 GMT) along a sidewalk adjacent to the metro station and the entrance to the Pentagon, officials said. After a hijacked plane slammed into the Pentagon in the September 11 attacks of 2001, the building was fortified and the metro entrance was rebuilt to bolster security. A metro escalator once connected directly to the Pentagon building entrance but that was closed after the 9/11 attacks. The shooting occurred hours after Danish Defence Minister Gitte Lillelund held talks at the Pentagon with US Defense Secretary Robert Gates to discuss the NATO-led war effort in Afghanistan.
