Pakistan has imposed lockdown-level, ultra-strong security measures in consideration of the possibility of a second U.S.-Iran meeting.
According to local outlets including the Express Tribune, Dawn, and Geo TV on the 19th (local time), Pakistani authorities issued a red alert from that day in major areas around Nur Khan air base in Rawalpindi, a city adjacent to the capital Islamabad, and around Islamabad International Airport ahead of the meeting.
All public transportation, private traffic, and freight transport in Rawalpindi have been suspended, more than 10,000 police officers have been deployed, and over 600 checkpoints have been set up to monitor every access point into the area. Local police said 400 commandos, including 100 snipers, have been mobilized and a 24-hour, multi-layered security system is being operated through CCTV and other means. Police officers, including snipers, have been stationed on the rooftops of each building, and flights of unmanned aerial vehicles (drones) and even the release of pigeons are completely banned.
Islamabad, expected to be the venue for the meeting, is also in a near-lockdown state of heightened security. City authorities have suspended public transportation and heavy equipment operations until further notice, and along major roads they are checking the security status of dwellings, shops, and commercial buildings, and have banned parking and entry by anyone other than meeting personnel. Movement on rooftops, balconies, and around windows of buildings in the area is also restricted, and violations will be the responsibility of the building owner.
Authorities also notified operators of student and office worker dormitories, hotels, inns, and guesthouses across the capital region to close their buildings until further notice, and announced that strict legal action would be taken for noncompliance.
Authorities are also considering closing Islamic seminaries near high-risk security zones and evicting students. They have prepared to lease containers from private businesses to block roads in an emergency.
After accepting Pakistan's proposed "two-week cease-fire plan" on the 7th, the United States and Iran set a deadline of the 21st U.S. Eastern time (the 22nd Iran time) and are reviewing options to end the war.
