Salman Masood, a correspondent of The New York Times, live-tweeted the raid, saying he had been told by a senior police official that a "terrorist search operation" was under way in his house. When he refused to let them in without a warrant, they left but returned later with an officer.

Pakistan's interior ministry has ordered an investigation into the raid. "Such raids and activities are not acceptable," a government statement quoted Interior Minister Chaudhry Nisar as saying.

The search comes at a time Pakistan claims to have raided and arrested a few persons in connection with the terror attack in Pathankot in India on January 2.
Mr Masood has posted photos of uniformed men searching his home. "They asked if I had any illegal weapons hidden in the house," he tweeted.
His tweets have drawn outrage.
