The attack on the Lahore police training centre on Monday was similar to the Mumbai terror strike, Interior Ministry chief Rehman Malik said while the attack was in progress.
Malik told Geo TV that the terror strike in Lahore was similar to the November 26-29, 2008 carnage in Mumbai that left about 170 people dead.
Last year, nine terrorists from Pakistan were killed and one arrested by the security forces that battled them for 60 hours at several locations, including a busy railway terminus, luxury hotels and a Jewish centre, all in south Mumbai.
While Monday's attack was going on, Malik said: "This is an attack on the country by forces which do not want to see Pakistan stable. There should be unity at political level and all level."
He said that Pakistan has been hit by a "wave of terrorism", adding the terrorists were trained and "used terror as a weapon".
Malik admitted that the police training centre that had been attacked was not secure and said that these buildings were not designed to prevent terror strikes. "New buildings will have enhanced security."
