NEW DELHI: India’s foreign ministry condemned an attack of an Indian-flagged ship off Oman as “unacceptable” on Thursday, with maritime security monitors reporting the cargo vessel had sunk.

New Delhi did not give further details on the attack on Wednesday, and the fate of the unnamed ship, nor who it believes was responsible.

“The attack on an Indian-flagged ship off the coast of Oman yesterday is unacceptable, and we deplore the fact that commercial shipping and civilian mariners continue to be targeted,” India’s foreign ministry said in a statement.

“All Indian crew on board are safe, and we thank the Omani authorities for rescuing them,” it added, without giving further details.

Maritime security firm Vanguard named the cargo vessel with 14 crew as the MSV Hajj Ali, and said it had reports that it had sunk off the coast of Limah, Oman — just south of the Strait of Hormuz — after an explosion.
