An explosion at a cultural center in the Turkish town of Suruc near the Syrian border has killed at least 28 people, according to the Turkish Interior Ministry.
The ministry said around 100 people were injured and are being treated in local hospitals.
The cultural center is around 10 kilometers away from the Syrian border town of Kobani.
In a written statement, the Turkish Interior Ministry called the blast a “terrorist attack.”
Two senior Turkish officials told Reuters evidence suggests the Islamic State militant group was behind the attack.
According to news reports, 300 people from the Federation of Socialist Youths association were staying at the center ahead of a planned trip to Kobani to help with the rebuilding.
Kobani was the biggest defeat for the Islamic State militant group and has since become a symbol of Kurdish resistance against the group.
In June, IS attacks on Kobani killed more than 200 people.
Shortly after the blast in Suruc, a suicide bomber detonated a car bomb at a checkpoint in Kobani’s south, killing two Kurdish soldiers, Rami Abdel Rahman, director of the Syrian Observatory for Human Rights, told AFP.
