GENEVA: Swiss judicial authorities said on Tuesday they had closed a money-laundering case against Pakistani presidential candidate Asif Ali Zardari and released $60 million frozen in Swiss accounts over the past decade. Daniel Zappelli, Geneva's chief prosecutor, said that he had no evidence to bring Zardari, 55, the widower of former prime minister Benazir Bhutto, to trial. Pakistan's government recently dropped out of all related cases it had initiated in Switzerland, saying the couple could not be accused of corruption, he said. Zappelli said the full $60 million in assets, seized at the request of the Pakistan authorities, had been released.
