A US Navy destroyer in the Persian Gulf\'s Strait of Hormuz struck a Japanese oil tanker Sunday, military officials said. In a brief statement from the Pentagon, the Navy said no one was injured when the USS Porter collided with the MV Otowasan north of the United Arab Emirates around 1 a.m., CNN reported. Neither ship was in danger of sinking and the Navy said its guided-missile destroyer was \"able to operate under its own power.\" The statement said the collision was not combat-related and was being investigated. The bulk oil container ship the destroyer hit carries a Panamanian flag, but is owned by a Japanese conglomerate. The Porter is part of the US 5th fleet and is on scheduled maritime security deployment, the Navy said.
