Two suspected US missile strikes, one using multiple drones, killed 17 people in a Pakistani tribal region along the Afghan border Thursday, local intelligence officials said.
The officials said the second, bloodier attack involved five drones and 10 missiles - an unusually intense bombardment.
The missiles rained on North Waziristan, considered a safe haven for many militants including groups determined to push the US and NATO out of Afghanistan. The strikes in North Waziristan are especially sensitive because they risk angering Afghan-focused militant groups who have agreed to be neutral as Islamabad cracks down on Taliban fighters who have threatened the Pakistani state.
It was not immediately clear who or what was targeted in the strike.
