PESHAWAR - At least 12 persons were killed in a suicide attack in Jandola, Frontier Region, connecting South Waziristan with Tank District of NWFP. As per details, after a long period of lull it was the first suicide attack in the main bazaar of Jandola Thursday morning as a youngster entered a hotel and blew himself up with explosives strapped around his body. The officials confirmed killing of six persons but independent sources informed that 12 people were killed and 25 injured. Officials also confirmed the attack but they termed it an outcome of rivalry between two militant groups in the area. Both the groups are engaged in hostilities since long. The recently emerged Zainullah group has levelled serious allegations against TTP chief Baitullah Mehsud and his associates. Both the sides are now involved in trading allegations against each other, causing widespread unrest amongst the local people. It merits mentioning here that recently the rival militant groups headed by Mullah Nazir and Baitullah Mehsud announced establishment of a Mujahideen body. Since such a decision, overall situation in both North and South Waziristan seems normal. But after the United States decision of declaring head money on Baitullah Mehsud, Abu Yahya Al Laibi and Haqqani network, violence has once again erupted in the region. Agencies add: A TTP spokesman claimed responsibility of the suicide attack. Around 25 people were wounded, and several of them were in serious condition in hospital, Barkatullah said. Local government official Farzand Ali Khan said the bomber targeted members of a peace committee, led by Haji Turkestan, which groups together tribesmen opposed to the Taliban and allied to the Pakistani authorities. Turkestan, who survived at least four attacks last year, is a pro-government tribal elder from Jandola, near the South Waziristan tribal area. He was previously allied to Baituallah Mehsud, country's most-wanted militant, but later joined a peace committee with his Bhotani tribe to support the government's anti-militant drive, the local official said. Turkestan's men were sitting in the compound when the bomber arrived. One of his supporters grabbed the attacker, who then blew himself up, witnesses said. "Tehreek-e-Taliban claims responsibility for the suicide attack in Jandola, aimed at Turkestan," spokesman Maulvi Omar said in a telephone call from an unknown place to reporters in the tribal district of Bajaur. Mehsud spokesman Maulvi Umar called the suicide attack revenge for clashes last year. "Turkistan Bitani's fighters killed 35 of our people last year, and we killed his people today in a suicide attack," Umar told a foreign news agency by phone. Umar further condemned the US bounty for his commander, saying: "God will protect Baitullah Mehsud."
