Seventy-year-old twin brothers riding bicycles were hit by trucks and killed in separate accidents two hours apart on the same highway. The first accident occurred at 9:29 a.m. on Tuesday when one of the twins was riding on an icy road in Raahe, 370 miles north of Helsinki, Constable Pauli Ketonen said. He said that a little more than two hours later the man's twin brother was killed by another truck about a mile from the first accident. It was unlikely that the second victim knew of his brother's accident, he said, because the police had not yet informed the family.
