ISTANBUL (Reuters) - Turkish authorities last week detained 1,682 people for questioning over suspected links to militant organisations and arrested 516 of them, the interior ministry said on Monday.

People suspected of links to the Muslim cleric Fethullah Gulen, who Ankara says orchestrated an attempted coup in July, made up the biggest number, with 1,096 detained and 426 of those arrested.

A total of 508 people were detained for links with Kurdish militants and 78 of those arrested, the ministry said. Authorities detained 78 people for links to Islamic State and arrested 12, it said.
