An Indian-flagged cargo vessel sank in the Red Sea on Monday after being struck by what appears to have been an explosives-laden boat off Yemen, marking another escalation in the growing threat to commercial shipping in the region.

India’s Minister of Ports, Shipping & Waterways, Sarbananda Sonowal, said the mechanized sailing vessel Faize Noore Oliya was hit by a projectile near Yemeni waters, causing it to capsize and sink.

“India strongly condemns this unprovoked attack on the defenseless mechanised sailing vessel,” Sonowal wrote on X. “The safety of our people is our supreme priority.”
