A fire erupted on the Indian Navy warship INS Brahmaputra while it was undergoing maintenance at the naval dockyard in Mumbai, officials reported on Monday. The incident has resulted in one junior sailor missing, with rescue operations underway to locate him.

The fire broke out on the multi-role frigate during its refit at the Naval Dockyard. The crew, along with firefighters from the dockyard and nearby ships, managed to control the blaze. Subsequent actions, including thorough checks for any lingering fire hazards, were swiftly executed.

"The fire was brought under control by the ship's crew with the assistance of firefighters from the Naval Dockyard, Mumbai and other ships in harbour, by [Monday] morning. Further, follow-on actions including sanitisation checks for assessment of residual risk of fire were carried out," the navy stated.

However, by the afternoon, the ship began listing heavily to the port side. Despite extensive efforts, the ship could not be stabilized, sources informed India Today TV.

"The INS Brahmaputra continued to list further alongside its berth and is currently resting on one side," sources added. Fortunately, no casualties have been reported.

The Indian Navy has initiated an inquiry to investigate the cause of the accident.
