A Turkish newspaper says a prominent journalist who is critical of the government has been beaten by four assailants outside his home, weeks after a ruling party legislator was caught on video threatening attacks.

Police say four suspects have been arrested.

Hurriyet newspaper said Thursday its columnist, Ahmet Hakan, suffered a broken nose and cracked ribs in the attack late Wednesday.

The newspaper said the four assailants had followed the journalist to his home from a television station where he moderates a political debate program. They assaulted him as he left his car.

Last month, Hurriyet's headquarters was vandalized by a mob following verbal attacks on the newspaper by President Recep Tayyip Erdogan.

Media rights advocates accuse Turkey's government of stifling media freedoms.
