Internal rift led to the killing: Saudi paper

US troops were led to al-Qaeda leader Osama bin Laden by his own deputy, Ayman al-Zawahiri, because of a simmering internal power struggle, a Saudi newspaper reported yesterday.
Al-Watan newspaper, quoting an unnamed "regional source," said the top two al-Qaeda men had differences and that a courier who led US forces to bin Laden was working for Zawahiri.
