Narrative:

We were cleared to descend to 8000 ft and to turn south to follow another air carrier aircraft. With the aircraft in sight, we were cleared to follow it. At this time we did not have the airport in sight. While programming the FMGS, we lost sight of the aircraft in the city lights. The visual approach was continued to 4000 ft. The GPWS alert came on 'terrain.' the captain immediately started a climb up to 5000 ft. ATC advised us of the terrain elevation and to climb to 5000 ft. After a short vector, we got the runway in sight and made a normal landing.
