New reports indicate that the terrorist organization ISIS as a prime suspect in the tragic bombings that hit Ankara, Turkey on Saturday.

ABC News reports that, while no group has yet claimed responsibility for the deadly attack, the Turkish prime minister says the country is closing in on a suspect, and that ISIS is the top priority of the investigation.

"It was definitely a suicide bombing," Prime Minister Ahmet Davutoglu said. "DNA tests are being conducted. It was determined how the suicide bombers got there. We're close to a name, which points to one group."

The Turkish government has detained over 50 suspects with possible ties to the Islamic State terror group, conducting multiple anti-terrorist raids throughout the country.

The prime minister said the country has had experience dealing with suicide bombers in the past, and that these attacks would not threaten Turkey's stability.

"This attack will not turn Turkey into a Syria," he said.

The two suicide bombings -- which targeted a public protest advocating peace between Turkish security and the Kurdistan Workers' Party (PKK) -- were the deadliest in the country's modern history. At least 97 people were killed by the blasts, although the pro-Kurdish Peoples' Democratic Party (HDP) puts the number at 128. 250 others were wounded.

This is not the first time a pro-Kurdish event has been the target of terrorist attacks. According to CNN, at least three bombings have hit Kurdish rallies this year alone, with one attack in the Syrian border town Suruc resulting in 34 deaths.

ISIS has been frequently blamed for these attacks, although the group has not claimed responsibility, which is unusual. Some have suggested that this may be an attempt to pit certain groups against one another.

The Turkish government has been a frequent combatant of the PKK militant group since their ceasefire ended in July. The Turkish news agency Anadolu reported 49 PKK members were killed in airstrikes over the weekend.

The HDP released a statement accusing the Turkish government of escalating the violence to influence the country's elections, which are three weeks away.

"Their public statements show a readiness to blame the victims of this attack and our party. Such a political tendency also shows that those responsible for this massacre will also be not brought to justice, and that even the investigation may be hidden from public scrutiny," the statement said.
