Ukrainian prosecutors arrested the captain of a ship which sank en route from Istanbul to Ukraine's Crimean peninsula and charged him with breaking transport safety laws. The Pamyat Mercuria (Memory of Mercury) sank during a storm on Friday, killing 14 people. Rescuers plucked 32 survivors from lifeboats and rafts in the Black Sea on Sunday and Monday, after days spent floating in the cold waters. Ships and aircraft were still searching the sea off the southern tip of the peninsula on Tuesday for five people still missing. "The captain of the ship Leonid Ponomarenko is currently in custody," Volodymyr Rebrov, Crimea's deputy public prosecutor, told reporters. If found guilty Ponomarenko could face up to 15 years in prison.
