ISLAMABAD - A rocket attack on a checkpost of security forces in South Waziristan tribal region sparked clashes that have left a soldier and 10 people dead, officials said Sunday.

Ten more people were also injured in clashes in Wana, headquarters of South Waziristan, they said.
Militants fired eight rockets on a security checkpost at Wana late Saturday night, killing a soldier and injuring three others.
The security forces launched an operation against the militants in Wana bazaar early Sunday, killing at least 10 people. Seven others were injured, officials said. It was not clear who were killed in the security forces operation. Some tribesmen claimed that civilians, including two women, were among the dead.
An official also confirmed killing of two women but he did not clarify how the women were killed. Local tribesmen said that firing of rockets had started late Saturday night and continued till Sunday morning. Both sides attacked each other.
 The security forces closed all roads to Wana bazaar and no one was allowed to enter the town. Sources said Wana bazaar had completely been closed and contingents of the army were patrolling the city.
Wana is the stronghold of Mulla Nazir group of Taliban, which has struck a peace deal with the government.
The area has been relatively peaceful for several years and locals said that members of Tehrik-e-Taliban Pakistan (TTP) had sneaked into the area in recent weeks, causing tension.
The security forces launched a major operation against the Tehrik-e-Taliban Pakistan  in October 2009, clearing most parts of South Waziristan of Taliban militants.
