An explosion has killed at least 27 people and wounded nearly 100 in the Turkish town of Suruc near the Syrian border, the interior ministry says.
The blast occurred in the garden of a cultural centre at about 09:00 GMT. Hundreds of youth workers were reportedly staying there.
Officials are investigating the possibility it was a suicide bombing.
Suruc, located near the Syrian town of Kobane, houses many refugees who fled fighting there in recent months.
Kobane has been a battleground between militants from the Islamic State (IS) group and Kurdish fighters since September last year, when IS overran the town, forcing most of its residents to flee into Turkey.
The Federation of Socialist Youth Associations (SGDF) is reported to have had at least 300 members staying at the Amara Culture Centre to take part in rebuilding work in Kobane.
Pervin Buldan, a senior lawmaker from Turkey’s pro-Kurdish HDP opposition party, told Reuters that local officials were investigating the possibility it was a suicide bombing.
“Turkish and Kurdish youth had come to cross into Kobane, and there were three or four days of activities planned,” she said.
The hashtags #SuruçtaKatliamVar (There is a massacre in Suruç) and #SuruçMassacre started trending on Twitter soon after the explosion.
Enis Senerdem from the BBC’s Turkish service said Kobane had become more stable recently after months of fighting, with Turkish groups trying to reach out and help people rebuild.
