Witnesses say two loud explosions have rocked the Pakistani town where Osama bin Laden was killed in a U.S. raid.

The source of the blasts in the town of Abbottabad was not immediately clear. An Associated Press team at the compound where bin Laden was living before the April 29 raid saw no signs of unusual activity Sunday.

There had been speculation that authorities might demolish the house in Abbottabad to try to stop the intense media attention on the town.
