WASHINGTON - US Republican presidential candidate Rick Santorum said on Wednesday that radical Shi'ite Muslims in Iran and Iraq believe in an 'apocalyptic version' of Islam that he called a 'death cult.' Santorum, a former US senator from Pennsylvania whose popularity among Republicans hovers in the low single digits, made the comments during a televised debate while assailing the international deal to curb Iran's nuclear program. Santorum said more than two-thirds of Iranian and Iraqi Shi'ite Muslims 'believe that the end of the world is going to come within their lifetime' because 'their regime preaches it.'
