In Pakistan, the Taliban has claimed responsibility for Monday's attack on the UN World Food Programme offices in the capital Islamabad. <br/><br/>A Taliban spokesman said that the international agency was targeted because their work was not in the interest of Muslims. Five persons were killed and six others injured as a suicide bomber dressed in military uniform blew him up in the office. Pak Interior Minister Rehman Malik said an investigation has been launched into the security officials who allowed the bomber to enter the WFP offices.
