The Tehrik-e-Taliban Pakistan ( TTP) has avenged the assassination of its leader Maulana Ali Sher Hyderi with the blasts in Shia's mourning procession in Lahore, a spokesman of the disbanded outfit said. Both TTP and a sister banned radical organization Lashkar-e- Jhangvi Al-Alimi have claimed the responsibility of the triple blasts in the eastern city on Wednesday night, killing 37 people and injuring over 200. The chief of Sipah-e- Sahaba Pakistan (SSP), Maulana Hyderi, was gunned down in August 2009 by unidentified assassins in Khairpur. "We have avenged the death of leaders and Ulema who have been killed at the behest of infidels," said TTP spokesman Qari Hussain, referring to Wednesday evening's three consecutive explosions including two suicide bomb attacks targeting a Shia mourning procession in Lahore. "This was a revenge, and we will also avenge the murder of other Ulema and party activists soon," Qari Hussain told media in a telephone call. Referring to the United States recent declaration of putting TTP on foreign terrorists list and announcing 5 million dollar reward for arrest of its two leaders, Qari Hussain commented that the Jews and Christians are enemies of Muslims and "Jihad will continue against them." Lashkar-e-Jhangvi Al-Alimi, an extremist Sunni terrorist organization is still holding the custody of two kidnapped people that include a British journalist Qureshi and a former Inter- Services Intelligence (ISI) official Col. Imam in their custody. In Lahore, a complete shutdown has been observed since Thursday to mourn the demise of innocent people after the government of Punjab province declared three days of mourning.
