Pakistan has expelled a reporter for the New York Times magazine who interviewed Taliban leaders and visited the southwestern Baluchistan province on the Afghan border, a media watchdog said.

The journalist, Nicholas Schmidle, whose report "Next-Gen Taliban" appeared in the magazine on the weekend, was deported on Friday, the Committee to Protect Journalists (CPJ) said. "The article contained interviews with anti-government Taliban leaders and was written from the tumultuous Baluchistan province, and its capital, Quetta," the New York-based watchdog said.

The Committee quoted Scott Malcomson, Schmidle's editor at the magazine, as saying that no explanation was given for the journalist's deportation. However, he said, the deportation was "clearly connected to his writing rather than anything else he was doing".

An information ministry official said Schmidle did not have a journalist visa. "He was on a two-year fellowship here and had visited sensitive areas in Baluchistan without permission and did reporting. He was not on a journalist via," the official said on condition of anonymity.
