Two Pakistan Navy personnel, Shoaibur Rehman and Ghufran Nasar, were killed while conducting a security patrol at sea, the navy's public relations directorate announced on Wednesday. The deaths occurred in the context of Operation Muhafizul Bahr, a naval security mission launched in March to protect Pakistan's shipping lanes amid rising regional tensions following the outbreak of US-Iran hostilities. The loss is particularly significant given that roughly 90 per cent of Pakistan's trade passes through sea routes, underlining the high-stakes nature of the patrols.
