A high alert has been sounded by the Pakistan government following intelligence reports that "five terrorists" were out to strike "somewhere" in the country, much on the lines of a suicide bomber who killed 42 army recruits in Dargai tribal area last Wednesday.
All provincial governments and the Islamabad Capital Territory administration had been directed to place security forces on high alert, Dawn quoted officials as saying.
"We are taking no chances. The tightened security will ensure that an intending attacker finds it difficult to carry out suck an attack," a senior police official said.
On Thursday night in Islamabad, about 150 personnel of Pakistan Rangers and a large number of the Frontier Constabulary troops were deployed along the Margalla Road and at embassies of Norway, Denmark and China.
The green area was combed by the Rangers. Earlier, 300 personnel of Pakistan Rangers and additional contingents of police were deployed at sensitive places in Islamabad, he said.
"Even those who hang about on roads are being told to move on by the security personnel," an official said.
Security personnel in civvies have also been deputed to keep a vigil on passengers and other people looking suspicious.
The localities of Afghan nationals, particularly Karachi Company, have also been combed.
