Around 2,000 security personnel, including sharpshooters from the elite National Security Guards, will keep a tight vigil on the national capital during Pakistan President Asif Ali Zardari's visit on Sunday.
Zardari will land in Delhi on Sunday morning and head to Prime Minister Manohan Singh's official residence where the two leaders will have a one-on-one meeting followed by lunch. From there, he will leave for Ajmer.
A senior police official said elaborate security arrangements have been made and security personnel have been deployed on the route from the airport to the Prime Minister's residence.
Sharpshooters will be deployed on the high-rises on the route, he said.
