After vows to respect sovereignty, U.S. strikes in Pakistan

A U.S. missile strike Wednesday in Pakistan further inflamed relations between the two anti-terrorism allies, just hours after the American military chief vowed to "respect Pakistan's sovereignty."

The strike against suspected militants in Pakistan's tribal area, which runs along the Afghan border, is thought to be the sixth such attack this month. It came as Washington is demanding that Islamabad do more to prevent Taliban and al Qaida extremists from using its territory.

Pakistani leaders have condemned the U.S. military interventions, which include the first documented American ground raid in the country earlier this month. The strikes have caused an uproar in Pakistan
