Suicide Attacker Kills 54 in Pakistan

A suicide attacker blew himself up among a Shiite rally in Pakistan's Quetta city on Friday, killing at least 54 people

This is the second major attack in Pakistan in the past few days in a condition while the country is facing severe flood crisis.

Pakistani Taliban have claimed responsibility for the blast and said the bombing was a revenge for the killing of radical Sunni clerics by the Shiites, and added that they would launch attacks on the United States and Europe.

Pakistani Taliban has repeatedly threatened to strike western targets in response to NATO's drone attacks that have targeted their sanctuaries in Pakistan.

The United States has condemned the Quetta attack and expressed solidarity with the people of Pakistan, calling it a "reprehensible" attack because it came during the Muslim holy month of Ramadan.

The Pakistani Taliban also claimed responsibility for bomb attacks on Wednesday at a Shiite march in the country's eastern city of Lahore in which at least 33 people were killed.

The attack came just three days after the United States added the Pakistani Taliban to its list of "foreign terrorist organisations" and charged its leader, Hakimullah Mehsud, with plotting an attack that killed seven CIA agents at a US base in Afghanistan on December, 2009.
