akistan's interior minister has urged the country to unite against insurgents after gunmen launched a deadly attack on a police academy in Lahore.
Rehman Malik said the country had a choice between letting the Taleban take over and uniting to fight them.
He also pointed the finger at other extremist groups, while suggesting that a foreign state may have been involved.
Security officials are interrogating at least four suspects captured after the attack, police say.
There was no immediate claim of responsibility for Monday's attack, which left at least 18 people dead.
Two civilians, eight policemen and eight militants were killed, and 95 people injured, during the eight-hour battle to wrest back control of the academy, according to the interior ministry.
Less than a month ago, gunmen attacked the Sri Lankan cricket team in Lahore, killing six policemen.
Until this year, the city, Pakistan's cultural capital, had remained relatively free of post-9/11 militant violence.
But Pakistan's militants appear to be running riot, the BBC's Damian Grammaticas reports from Lahore.
