Divers resumed their search Sunday morning for up to 50 people unaccounted for after a luxury Italian cruise ship ran aground off the coast of Tuscany, killing at least three people and injuring 20 others, authorities said.
There were fears the death toll could rise as rescuers searched the Costa Concordia and surrounding waters for others who may have been trapped after rocks tore a gash in the hull Friday evening, causing it to turn over on its side off the coast of the island of Giglio.
The ship's captain, Francesco Schettino, was detained later Saturday for investigation of abandoning ship and manslaughter, Francesco Verusio, a chief prosecutor, told Italy's ANSA news agency.
