TTP denies Boston Marathon blasts

MIRANSHAH: The Tehreek-e-Taliban Pakistan (TTP), which claimed the 2010 Times Square bomb plot, on Tuesday denied anything to do with explosions that killed three people and wounded more than 100 in Boston.

"We believe in attacking US and its allies but we are not involved in this attack," TTP spokesman Ehsanullah Ehsan told.

"We have no connection to this bombing but we will continue to target them wherever possible," Ehsan added.

Monday's explosions at the Boston Marathon, one of America's top sporting events, forced cities from New York to Los Angeles to go on high alert and conjured up memories of the September 11, 2001 attacks.

US President Barack Obama says it is not yet clear who was behind the blasts. He said the perpetrators would pay. He did not utter the word "terror".
