Terrorism

ISLAMABAD, Pakistan (AP) — Two suicide bombers blew themselves up at the gates of Pakistan's main weapons complex Thursday, killing 59 people and wounding 70, officials said. A Taliban spokesman claimed responsibility for the attack, one of the bloodiest yet in Pakistan's intensifying war with insurgent groups that are also destabilizing Afghanistan. Pakistani forces are involved in an escalating battle with Islamic extremists in two nearby regions of the country's violence-plagued northwest, despite government efforts to negotiate peace with extremist groups. Maulvi Umar, a spokesman for Tehrik-e-Taliban Pakistan, a militant umbrella group, said the suicide bombings were revenge for airstrikes in Bajur, a militant stronghold near the Afghan border.
