Turkish anti-terrorism police have detained dozens of individuals linked to a Kurdish opposition party in country-wide raids, according to state media.
The reports did not specify whether the individuals detained were suspected of involvement in Saturday's bombing near the Besiktas football stadium in Istanbul in which at least 38 people were killed and 155 others injured.
The state-run news agency said at least 37 members of the pro-Kurdish People's Democratic Party, or HDP, were detained in Istanbul and the capital, Ankara, early on Monday.
The state-run television channel TRT reported similar raids, saying 58 were detained in the port city of Mersin and 51 in Sanliurfa in the south-east.
President Recep Tayyip Erdogan and other Turkish authorities accuse the HDP of having ties to the outlawed Kurdistan Workers' Party, or PKK.
