Bulgaria has detained five people suspected of aiding the attackers
Five people have been detained in Bulgaria in connection with the fatal bombing in downtown Istanbul, Siyka Mileva, a spokeswoman for the Bulgarian Prosecutor General's office, said on Saturday.
According to the broadcaster BNT, three of the detainees are Moldovan nationals, while the other two, a man and a woman, are of "Arab origin." They were charged with helping the perpetrator of the attack flee Trkiye by offering logistical support and communication.
A bomb went off on a popular tourist street in Trkiye's largest city on Sunday, killing six people and injuring more than 80.
The Turkish authorities said that the Kurdistan Workers' Party (PKK), a Kurdish group listed as a terrorist organization by Trkiye, the US and EU, was responsible for the attack. The PKK denied any involvement.
On Friday, a court in Istanbul authorized the jailing of 17 suspects pending trial, including a Syrian woman named Ahlam Albashir, who is accused of planting explosives at the scene.
