Fishermen missing after destroyer slices boat in two

A father and son are missing after a Japanese navy destroyer equipped with advanced radar ploughed into their fishing boat off the Pacific coast early today, splitting the vessel in two and hurling them into the chilly water.

The coastguard and navy deployed 10 ships, including the destroyer, and six helicopters to search the waters off the coast of Chiba, near Tokyo, for the two men, said Keiji Oba, a regional coastguard official.
