The armed militants targeted the World Vision office in Mansehra district in the Northwestern Frontier Province (NWFP). Even though the NWFP is troubled by the presence of terror groups such as the Taliban, Mansehra is a relatively peaceful district.
While the police claim that five people, including two women have been killed, a charity worker told a news agency that six people were killed while six others were gravely injured in the attack.
The militants, who unleashed the attack on the charity organisation building also clashed, with the police personnel, who arrived at the site when they got the information on the attack.
It can be recalled that a similar attack was launched against the British-run aid group Plan International in Feb 2008. Four local staff were killed in the strike and the office was burned down by the attackers who were armed with guns and grenades.
This attack had prompted some of the charities to leave the country.
