Bomb, grenades hit 2 mosques in Pakistan; 53 dead

PESHAWAR, Pakistan  —  Three grenade blasts killed at least three people at a mosque in northwestern Pakistan during afternoon prayers Friday.
Earlier in the day a suicide bomber struck a mosque frequented by anti-Taliban tribal elders in the troubled Afghan border region killing at least 50 people in one of the deadliest attacks this year.
The blasts were the latest to hit religious gatherings and underscored the relentless security challenge in the U.S.-allied nation, where Islamist militants have managed to strike at the state and citizens who work against them despite pressure from army offensives.
