(AP) -- The State Oceanic Administration said late Monday oil slicks around the site of the sunken ship were much larger than the previous day.

It says a 15-kilometer (9-mile)-long oil slick was found southwest of the site as well as another one that stretched for 18 kilometers (11 miles) east of it.

The Chinese transport ministry said Monday the fire from the sunken ship had burned out.

Concerns remain about possible major pollution to the seabed and surrounding waters.
