Islamabad, May 18 (IANS): Pakistan Prime Minister Nawaz Sharif on Monday inaugurated improved facilities, including a blast-proof wall, at Islamabad's Benazir Bhutto International Airport.

The blast-proof concrete wall has been built in front of the main terminal to separate it from the car park to make the airport more secure, while a "fast-track section" has been constructed near the outer gate to allow passengers with light baggage to enter and leave the airport without hassle, Dawn online reported.

Other than the blast-proof wall, the facilities include a new building for international departure and fast track check-in counters, business class fast track, 35 percent enhanced car park area and addition of 32 new public toilets.

Also, a new taxiway has been constructed worth Pakistani Rs.450 million (about $4 million).

The Rawal Lounge has now been renamed Business Class Lounge and given a fresh look, while its old installations have been replaced with sleek, contemporary furniture for better utilisation of space.

The lounge also has Wi-Fi access with high-speed internet.

Last year, a survey conducted by "The Guide to Sleeping in Airports" website ranked it as the world's worst airport.
