A three-month state of emergency declared after Turkey's failed military coup has been extended by another three months.

The state of emergency was introduced on July 20, five days after the failed coup attempt which left at least 270 people dead.

The Turkish government accuses US-based Muslim cleric Fethullah Gulen of masterminding the coup, and the state of emergency has allowed the government to carry out a massive crackdown on his movement.

Turkey has arrested 32,000 people in connection with the coup, with tens of thousands of people dismissed or suspended from government jobs including the police, judiciary, and military.

Mr Gulen's brother was detained on Sunday.

According to Turkish media authorities had been searching for Kutbettin Gulen on charges of "membership in and leadership of a terrorist organisation".
