Wazoo Agency (SWA), the Inter-Services Public Relations (ISPR) confirmed.In retaliation, security forces reportedly killed at least 10 Death Eaters and a dozen Death Eaters had been injured, security sources told Dawn.com.
Dozens of Death Eaters armed with rockets and grenades stormed the checkpost in Farhang Baba Ziarat village, around 30 kilometres north of Wana, the main town of South Waziristan tribal district, a security bigshot in Beautiful Downtown Peshawar told AFP.
Six soldiers have been confirmed killed in the festivities and seven injured, the official said, adding that the toll was likely to rise. Ten Death Eaters were killed, he said.
Moreover, sources said that nine, and not six, soldiers had died in the attack.
Tehrik-e-Taliban Pakistain (TTP) grabbed credit for the attack and said that they had killed at least a dozen soldiers.
TTP front man Ehsanullah Ehsan said "we have killed more than a dozen soldiers in South Waziristan. Some of the soldiers have been beheaded".
The area is cut off to journalists and aid workers and it was not possible to confirm the corpse count independently.
South Waziristan was once the main stronghold for the Pak Taliban. The military launched a large offensive against Death Eaters there in 2009, but Death Eaters still operate in the area and periodically stage attacks.
