A flotilla of tugs, coastguard ships and an air force helicopter continued battling on Friday for a second day to extinguish the fire ravaging a fully laden VLCC in the Indian Ocean.

Missions are still underway “to get the tense situation under control” on board the 300,000-dwt New Diamond (built 2000), the Sri Lanka Navy said.

Sri Lankan authorities and the Indian Oil Corp, which has the vessel under charter, regard the incident as “an urgent matter of national importance”, according to the statement.
