'Fire from US-led forces in Afghanistan kills 4 civilians in Pakistan'

US-led forces in Afghanistan fired across the border into Pakistan in a strike against Taliban militants, but the Pakistani army said Thursday that two women and two children were killed. Anger at civilian deaths and concern that they fuel extremism could persuade the incoming Pakistani government to ease off a US-backed policy of using military force to root out militants. But the attack also illustrates Washington's concern at how the Taliban and al-Qaida continue to use Pakistan's lawless border area as a base for attacks in Afghanistan. A suicide bomber rammed a convoy of US troops in the Afghan capital on Thursday, killing six civilians, while the American-led coalition said it killed a dozen militants in the southern province of Helmand.
