Turkey's largest-circulation newspaper has adopted a more pro-government line in its first edition since a court ordered it to be seized, a move which has heightened fears over deteriorating media freedom in the country.

The European Union is facing increasing pressure to speak out against the erosion of media freedom in Turkey following the takeover of the country's largest-circulation newspaper.

Police, using tear gas and water cannons, on Friday raided the headquarters of Turkey's largest-circulation newspaper, hours after a court placed it under the management of trustees.
