As residents of the U.S. Northeast grapple with the destruction wrought by Superstorm Sandy, an offer of assistance has come from an unlikely quarter: the leader of a radical Muslim group in Pakistan that Washington has branded a terrorist group.

"We offer our unconditional support and help for the victims" of the storm, Hafiz Mohammad Saeed, head of the Islamic charity Jamaat-ud-Dawa, said in a statement late Tuesday. "If U.S. government allows, we will send our doctors, relief and rescue experts, food and medicine on humanitarian grounds."

India accuses Saeed of masterminding the 2008 terrorist assault on Mumbai that killed 166 people - an allegation he denies.

The United States, which has declared Jamaat-ud-Dawa a terrorist organization and put up a $10 million reward for information leading to Saeed's arrest and conviction, declined the offer.
