MIR ALI, Pakistan -- Suspected American missiles slammed into a home and a speeding vehicle near the Afghan border Tuesday, killing 20 alleged militants as the U.S. ramps up unmanned drone strikes in northwestern Islamist strongholds, Pakistani officials said.
The eighth missile attack this month in Pakistan killed targets in North Waziristan, a mountainous tribal region that is a base for Taliban and al-Qaida-linked fighters responsible for many of the attacks on U.S. and NATO forces across the border in Afghanistan.
The U.S. has launched 100 such strikes in Pakistan so far this year, a major surge over previous years for the drone program that is rarely officially acknowledged by Washington. Nearly all have hit in North Waziristan, where Muslim extremists run a virtual mini-state outside the Pakistani government's control
At least four missiles were fired before dawn Tuesday in North Waziristan's Bangi Dar village, two at the mud-brick house and two at the vehicle, two Pakistani intelligence officials said. Four of the slain were in the vehicle, while at least 11 died in the flattened home.
The identity of the dead was not known, and agents were trying to get more details, said the officials. A different pair of security officials closer to the scene said later that at least 20 were killed. All spoke on condition of anonymity in line with official policy.
U.S. authorities want Pakistan's military to launch an offensive in North Waziristan, but Islamabad has resisted, saying it has its hands full with army operations against Muslim extremists trying to take control of territory elsewhere in the northwest.
Pakistan's U.S.-allied government publicly denounces the missile attacks as a violation of the country's sovereignty. It has asked Washington to transfer the technology to Islamabad so that the Pakistani army could launch such strikes on its own.
