A car bombing in south-eastern Turkey left three people dead, two members of the security forces and a civilian, while 19 militants died in clashes with government troops, according to media reports on Saturday.
The bomb blast took place near a security building in Mardin province, state-run Anadolu news agency reported. Meanwhile the pro-Kurdish Firat news agency also reported several deaths on the Turkish forces' side during clashes, as well as casualties from the car bomb.
In a shootout the previous day in Semdinli district of Hakkari province, 17 members of the armed Kurdistan Workers' Party (PKK) were killed, the agency reported.
Two additional militants were killed in the eastern Van province as the sides exchanged fire, Anadolu said.
The information from the news agencies could not be independently verified.
Kurdish militants and state security forces have clashed daily since a ceasefire broke down last July. Turkey's air force also carries out regular raids against the PKK in northern Iraq.
More than 40,000 people have been killed in the 30-year war between Turkey and Kurdish militants. The PKK is demanding greater autonomy for the large Kurdish minority in Turkey.
