The house arrest of Mumbai terror attack mastermind Hafiz Saeed has been extended by another month by authorities in Pakistan's Punjab province, saying his activities pose a threat to the peace and tranquillity in the country. <br/><br/>Saeed, the Jamaat-ud-Dawa (JuD) chief, has been under house arrest since January 31 this year. Punjab Home Department yesterday issued an order extending the house arrest of Saeed and his four aides – Abdullah Ubaid, Malik Zafar Iqbal, Abdul Rehman Abid and Qazi Kashif Hussain – for another 30 days with effect from September 25. <br/><br/>The previous order to extend his house arrest was issued on July 28. On January 31, Saeed and four others were put under house arrest by the Punjab government for 90 days under the Anti-Terrorism Act 1997. Meanwhile, Saeed today filed a fresh application in the Lahore High Court against the latest order extending his detention for another 30 days.
