Pakistan authorities on Thursday imposed a temporary ban on fishing in the country’s territorial waters. All fishing boats and trawlers currently at sea have been recalled as a precautionary measure. A high alert has also been issued at the country’s three major ports: Karachi, Port Qasim, and Gwadar.

The ban will remain in effect until the high alert is lifted. Authorities have urged fishermen to refrain from venturing out to sea, and security at all major ports has been significantly tightened.
