India's Ministry of External Affairs filed a formal protest with Pakistan's envoy today after warships from the two countries collided in international waters last Tuesday. A Pakistani warship approached an Indian frontline vessel at high speed while the Indian ship was conducting a routine patrol, leading to the collision. India's Ministry of External Affairs said the impact did not cause serious damage, but that Pakistan's conduct was a complete violation of a 1991 agreement between the two countries, which requires their warships and submarines to maintain a distance of at least 3 nautical miles from each other to avoid accidents in international waters. India and Pakistan previously engaged in four days of intense military conflict last year before reaching a ceasefire agreement later on. Currently, neither country has an ambassador stationed in the other's capital, as diplomatic relations were downgraded following the 2019 Kashmir territorial dispute, leaving their diplomatic missions to be overseen by deputy chiefs of mission ever since.
