An Indian tanker that ran aground off the coast of Saudi Arabia has spilled more than 1.3 million gallons of crude oil into the Red Sea, creating a giant slick that is "growing every minute," shipping sources said Friday.

Maritime executives in the Saudi Arabian port of Jeddah said the 276,744-ton supertanker Kanchenjunga leaked the crude into the sea after it ran aground on a reef Thursday about 6 nautical miles from the Yenbu terminal near Jeddah."(The Kanchenjunga) has been badly holed in several places on the starboard side and is leaking heavily into the sea," a maritime executive told United Press International by telephone. "She's leaked about five or six thousand tons of crude into the sea so far. There's a giant slick out there which is growing every minute."

Maritime executives in Jeddah said the tanker, owned by the state-run Shipping Corporation of India, was carrying a full load of 42 million gallons of crude oil when it ran aground early Thursday.
