Minister for Interior Rehman Malik Friday warned of strict action against challenging the writ of the government, saying that stern action would be taken if the writ of the government is challenged. Contradicting the media reports of the arrest of TNSM Chief Maulana Sufi Muhammad and TTP Chief Maulana Fazalullah, Rehman Malik told reporters here at the Parliament House that both reports were incorrect. Neither Maulana Fazlullah has been killed nor he or Maulana Sufi Muhammad have been arrested. Swat operation is going great guns and the situation for the return of the Internally Displaced Persons (IDPs) would be clear within next few weeks, he said.
