With morale boosted by recent reunions, families continue to protest in southeastern Turkey for the return of their children abducted by the PKK terrorist group.

Families have been camped for 699 days outside the pro-PKK Peoples' Democratic Party (HDP) headquarters in Diyarbakır province.

Ayşegül Biçer, one of the three mothers who started the sit-in protest on Sept. 3, 2019, was recently reunited with her son Mustafa, along with two other families, raising hopes for others still yearning for their loved ones' return.

Mevlüde Üçdağ, a mother at the protest, said the families are confident they will eventually be victorious and none of them will leave without getting back their children.

"Our fight will continue until not a single son or daughter is left in the mountains," she said.

Üçdağ called on her son, who she said was tricked by the HDP into joining the terrorist group, to immediately surrender to Turkish authorities.

Nurettin Ödümlü, a father, said his son Yusuf went missing eight years ago at the age of 16.

"We want our child back from the HDP. We will not leave until my son comes back," he said, accusing the party of being involved in his child's disappearance.

The protest started when Hacire Akar turned up on the doorstep of the HDP’s Diyarbakır office one night. Akar’s son Mehmet subsequently returned home on Aug. 24, 2019, giving hope to other families. A week later, on Sept. 3, 2019, families inspired by Akar transformed her solo stance into a collective sit-in protest.

Families have continued their stance under difficult conditions. They were sometimes threatened by HDP officials and even by people linked with the PKK terrorist organization. They have also not given up during the coronavirus pandemic, continuing sit-in protests while taking the necessary precautions.

A significant number of suspected terrorists have started fleeing the PKK and surrendering, while many terrorists lack the courage to leave the group because they would face severe punishment if caught. The dissolution of the PKK has accelerated due to Turkey's successful counterterrorism operations and strategies both at home and abroad. In recent years, Turkey has seen record numbers of PKK terrorists giving themselves up in the face of determined domestic and cross-border counterterrorism operations.

The families called on their disappeared family members to surrender to security forces.

With the latest additions, the number of terrorists who surrendered to Turkish security forces has reached 114 this year, the Interior Ministry announced last week, adding that it will mark the 31st time a protesting family reunites with their child. President Recep Tayyip Erdoğan called mother Ayşegül Biçer to congratulate her for reuniting with her son Mustafa, who joined the PKK in 2018 at the age of 17.

Mother Aynur Panay is among the protesters, and she joined the sit-in to bring back her son Emrah, who, she said, was abducted by the terrorist group at the age of 13 in the Doğubeyazıt district of eastern Ağrı province.

"My son was tricked by the HDP, handed over to the PKK ... I want my son back," she said, adding that the recent reunion of three mothers with their children was a source of joy for her and other protesting families.

"For God's sake, come back, surrender to the gendarmerie, police. I have been longing for you for a decade. I've missed you so much," she said.

Another protester, Abdullah Demir, said he is staging the sit-in for his son Fatih, who was abducted by the PKK.

"I've not abandoned my son for five years. I will be looking for him till my last breath," he said.

The HDP, long facing public scrutiny and judicial probes over its ties to the PKK, is under pressure from the growing civilian movement. Various groups from around Turkey have supported the Kurdish mothers in their cause, with many paying visits to show their solidarity.

In its more than 40-year terror campaign against Turkey, the PKK – listed as a terrorist organization by Turkey, the United States and the European Union – has been responsible for the deaths of 40,000 people, including women, children and infants.
