A U.S. drone strike killed at least four suspected militants in northwest Pakistan on Monday, four intelligence officials said, the fourth such strike this year. Two missiles hit a compound in the Shahi Khel area of Shawal Valley in North Waziristan, near the border with Afghanistan, the officials said. "Through our local sources and intercepts, (we know) a drone fired two missiles at a compound in the Shawal area and killed four militants. The number of dead may go up," an intelligence official told Reuters. The attack came a month after 134 school children were killed by Taliban insurgents, the worst single assault in the country's history.
