Two suicide bombers rammed their explosives-laden vehicle into the gate of an army base in South Waziristan, killing at least one soldier and wounding eight, security officials said on Wednesday.

The attackers, who drove in from Afghanistan, were stopped before they could get into the camp in the South Waziristan capital of Wana, where thousands of soldiers are stationed, army officials said.

"Security forces intercepted the car and opened fire as it neared the camp. The two men then blew themselves up," said one army official who declined to be identified.
