The U.S. Coast Guard says the Houston Ship Channel is closed after an early-morning tanker fire and oil spill. The Coast Guard says the tanker, The Aframax River, may have hit a submerged sewer line. This caused a rupture in the hull, leading to a fire. There were no injuries. The incident happened at about 2 a.m. Tuesday. The fire is out, but one mile of the ship channel remains closed at this time south of the Battleship Texas. Officials say there is a bunker oil spill, but it's not yet known how much oil was lost in the channel. They will assess the spill after sunrise and hope to hope the ship channel sometime after 9 a.m. Watch KHOU 11 News This Morning starting at 4:30 a.m. for live reports and check back here for updates.
