The Pakistani Taliban have claimed responsibility for a deadly suicide bombing at the heavily fortified U.N. World Food Program's headquarters in Islamabad, The Associated Press reported.
The bomber dressed as a security guard and blasted the building's lobby, killing at least five people just one day after the Pakistani Taliban’s newest leader had met with reporters and vowed revenge attacks, according to the AP.
The U.N. said it would close its aid office temporarily after the attack, the first to hit Pakistan’s capital since June.
On Sunday, militant Hakimullah Mehsud stood shoulder to shoulder with other top Taliban commanders in a show of unity to end speculation that the Taliban was divided and counter false reports of his death, the AP reported. Mehsud pledged in an interview to attack the U.S. and Pakistan in retaliation for scores of unmanned drone bombings along the Afghan border and the killing of Taliban leader Baitullah Mehsud.
