Turkey police raid Gulen-linked newspaper and TV station

At least 23 people have been arrested after Turkish police raided a newspaper and TV station with ties to US-based Islamic cleric Fethullah Gulen.

The government has accused Mr Gulen's movement of plotting to bring it down.

As Mark Lowen reports, Turkey's President Recep Tayyip Erdogan has pledged a fresh campaign against Mr Gulen's supporters.
