Three killed in Pakistan by 'US drone attack'
A US drone attack has killed at least three militants in Pakistan's tribal area, local intelligence officials say.
They say missiles hit a house just outside the town of Miranshah in North Waziristan, near the Afghan border.
The US made no official comment, but unnamed sources said it was a US drone.
If confirmed, it would be the first US air raid since November's Nato helicopter strike on the Afghan border killed 24 Pakistani soldiers, straining ties between Washington and Islamabad.
Sources in Washington indicated that a US-operated drone was fired a militant target on Tuesday.
After the November strike, Pakistan closed its border with Afghanistan, cutting off vital Nato supply lines.
A US military report later concluded that both sides had made mistakes during the incident, blaming poor information and inadequate co-ordination between US and Pakistani forces on the ground.
The Pakistani military said the report was "short on facts".
