Watch: Oil Tanker on Fire After Collision in East China Sea

An Iranian oil tanker is in danger of exploding and sinking after colliding with a Chinese freight vessel off China’s east coast. The oil tanker was transporting 150,000 tons, or nearly 1 million barrels, of oil to South Korea. Chinese rescue teams are attempting to control the blaze. The remains of one crew member have been found, and 31 are still missing. It's unclear how much oil has leaked into the sea, or what the potential environmental impacts will be.
