ANKARA (Reuters) - Turkey replaced the mayors of a Kurdish-majority town in its southeast with a state official, the pro-Kurdish Peoples' Democratic Party (HDP) said, amid a crackdown at home on criticism of Ankara's offensive in Syria.

The HDP said five of its co-mayors in the southeastern Kurdish-majority towns of Hakkari, Yuksekova and Nusaybin, had been jailed pending trial on Thursday. Two other co-mayors in the district of Ercis were detained earlier this week and remain in custody, it said.
