Rescue crews are racing against time to bring a blaze on an Iranian oil tanker under control, following a collision with a Hong Kong grain ship.

Iran's Foreign Ministry says the search for 30 missing Iranian crew members from the Panama-registered tanker Sanchi is continuing. Earlier on Monday, Chinese officials said that none of crew, including two Bangladeshi members, were found. The two vessels collided about 160 nautical miles off China's coast near Shanghai and the mouth of the Yangtze River Delta on Saturday evening. Search and cleanup efforts had been hampered by fierce fires that have engulfed the tanker and surrounding waters.
