Islamabad, Feb 17 (IANS): A day after the horrific suicide bombing at a Sufi shrine in Sindh province that left 88 people dead, the Pakistan Army on Friday claimed to have killed more than 100 militants in intelligence-based operations carried out by security forces across the country.

"The intelligence agencies are making progress to unearth networks behind the recent terrorism incidents," read a statement issued by the Inter-Services Public Relations.

In its statement, the military claimed that it had found linkages to militant support networks operating from across the border.

"The border has been closed since last night due to security reasons. No cross-border or unauthorised entry will be allowed into Pakistan from Afghanistan," read the statement.

The security forces have been given special orders to maintain strict vigilance all along the border, it added.

"The Army is for security of people of Pakistan against all types of threat. The nation should stay steadfast with full confidence in their security forces. We shall not let the hostile agenda succeed whatever it may cost," army chief General Qamar Javed Bajwa was quoted as saying.
