ISLAMABAD, Pakistan (CNN) -- The second suspected U.S. missile strike in two days killed four suspected Islamic militants in northwest Pakistan, intelligence officials said Friday.
The latest attack struck a compound located about 50 km (31 miles) from the Pakistan-Afghanistan border, the officials said. A nearby girl's school was also damaged in the strike, but there were no other reports of injuries, they said.
The strike occurred about 8:45 a.m. Friday (10:45 p.m. Thursday ET) about 30 km east of Wana, in the South Waziristan tribal district. South Waziristan is located in Pakistan's ungoverned tribal region along the Afghan border, where authorities on both sides are battling insurgents from the Taliban, the fundamentalist Islamic militia that once ruled most of Afghanistan.
A Thursday morning strike near Wana, also believed to have been conducted by a U.S. drone, killed three people that intelligence officials said were believed to be Uzbek fighters.
The U.S. military in Afghanistan routinely offers no comment on reported cross-border strikes, which are normally launched from unmanned drones. But the United States is the only country operating in the region known have the capability to launch missiles from drones, which are controlled remotely.
