Pakistani intelligence officials say an air strike by a suspected U.S. drone (unmanned aircraft) has killed at least six people in a northwestern tribal region near the Afghan border.
Officials said the missile struck a house next to a Muslim school in South Waziristan, in an area believed to be a stronghold of al-Qaida militants.
They said the identities of those killed in the strike were not immediately known.
There have been more than 30 missile strikes targeting alleged militants in Pakistan since August. They are believed to have been carried out by U.S. remote-controlled aircraft. U.S. authorities have refused to confirm or deny responsibility for the attacks.
The Pakistani government has strongly condemned the air strikes, saying they undermine Pakistan's counter-terrorism efforts.
