ISLAMABAD - Speaker National Assembly Dr. Fehmida Mirza rushed into meeting with Prime Minister Syed Yousuf Raza Gilani following receiving anonymous letter containing a threat of attack on Parliament House a few days back, Parliamentary sources informed TheNation on Tuesday. The sources further informed that the anonymous letter addressed to the Speaker National Assembly contained a threat of possible attack on the Parliament House in near future if the ongoing operation against what they termed Mujahideen was not stopped forthwith. It was further informed that soon after receiving the letter, Dr. Mirza had alerted the security of the Parliament House and brought the matter into the notice of Federal Interior Ministry Rehman Malik and Prime Minister Gilani. She also held detailed meeting in this connection with PM Gilani and it was decided in the meeting that the security of the Parliament House would not only be beefed up but the loopholes in it would be plugged on emergency basis. The sources further informed that soon Dr. Mirza would be getting a detailed briefing on the security set-up from all the concerned officials involved in providing security to the Parliament House. In the meeting the ways and means would be discussed to further beef up the security system of the Parliament and if required more staff would be deputed and barbed wire loops would be placed along the boundary grill of the Parliament House. It was after the receiving the threatening letter that even the armed guards of MPs were barred from entering the Parliaments premises and the security staff both at MPs entrance and general parking entrance was enhanced. At the general entrance of the Parliament House, the staff was further directed to note down the names of the visitors and also increase the vehicles checking to avoid any untoward incident. It is pertinent to mention here that almost a month back, Dr. Mirza, while chairing the session, had twice expressed concerns over the loopholes in the security of the Parliament and sought the help of MPs in this regard. She had also asked the Parliamentary leaders of all the parties in the Parliament to have a detailed meeting on the security of the Parliament House so that it could be made foolproof.
