HOUSTON (AP) _ A weekend oil spill caused by a collision between a ship and a barge closed the ship channel servicing the nation's second largest port.

The fuel oil spill occurred Saturday afternoon at Barbour's Cut in La Porte, Texas. The waterway reopened to traffic Sunday, Coast Guard officials said.

About 860 barrels of fuel oil leaked into the channel, said Hudson Marine Management Services officials who represent the owner of the ship, the New Amity.

About 18,000 feet of boom were set up to contain the oil and skimmers were removing it. Containment and cleanup operations involved more than 70 people, Hudson Marine officials said.
