Two bombs exploded at a rally near the main train station in the Turkish capital of Ankara on Saturday killing at least 86 people and injuring 186 others, authorities said.

The explosion occurred during a peace march involving the pro-Kurdish HDP, or People’s Democratic Party of Turkey.

Video showed bodies and injured people lying on the ground as bystanders tried to help the wounded.

Reports say the death toll is expected to climb. Death toll stood 30 people were killed before.

Turkish President Tayyip Erdogan said the incident was a terrorist attack.

“Like other terror attacks, the one at the Ankara train station targets our unity, togetherness, brotherhood and future,” Mr. Erdogan said in a statement.

The two blasts happened seconds apart in the morning as hundreds gathered for a planned march to protest over a conflict between Turkish security forces and Kurdish militants in the southeast.

No group has claimed responsibility for the attack yet, though people suspected either ISIS or Kurdish separatists in Turkey.
