SURUC, TURKEY -- The suicide bomber who killed more than 30 people in the Turkish border town of Suruc is thought to have been a 20-year-old Turkish national, an official in that country told CNN on condition of anonymity Wednesday.
Separately, Turkey's semiofficial Anadolu news agency reported Wednesday that the suspect's name was Seyh Abdurrahman Alagoz.
Turkish authorities have said they believe the terror group ISIS was involved in the explosion, which killed at least 31 people in one of the deadliest terrorist attacks to rock the country in years.
At least 100 others were wounded, provincial Gov. Izzettin Kucuk told Turkish media.
Suruc lies about 6 miles (9.7 kilometers) from the Syrian border opposite Kobani, the Syrian city that was the scene of intense fighting last fall between ISIS and predominantly Kurdish forces, backed by coalition airstrikes.
The suspect was from the southern Turkish town of Adiyaman, about 90 kilometers (56 miles) north of Suruc, the anonymous Turkish official told CNN.
Turkish Prime Minister Ahmet Davutoglu told a news conference Tuesday that "one suspect has been identified" and that all that person's "links domestically and internationally are being investigated."
"Right now, links to ISIS and it being a suicide bomber have gained probability," he said. "We expect the investigation to be completed as soon as possible."
Davutoglu on Monday described ISIS as "not just a threat to Syria but to Turkey as well."
