German parliamentarian Sevim Dağdelen from the Left Party (Die Linke) has been receiving death threats from far-right Turks, the party said.
Sarya Ataç, who was a candidate in local elections, also received such messages, Left Party lawmaker Jörg Schindler said. Both Dağdelen and Ataç are politicians of Turkish origin.
"Our party and our efforts for peaceful and democratic coexistence are under attack," Schindler said.
The death threats are sent with the name of JİTEM, a clandestine gendarmerie intelligence unit responsible for dozens of unsolved murders, predominantly in the 1990s.
"The Turkish government is tolerating this organization, to say the least," Schindler said, as he called on German authorities to take action on the issue.
"Authorities must urgently find the perpetrators and protect our women comrades," he noted.
