The commemoration will be attended by hundreds of Australians and New Zealanders.
The suspect named by local media as Abdulkerim Hilef and Turkish authorities said that he’s a 26-year-old Syrian national. A picture circulated online showed a young man with short hair and some facial hair.
The man was arrested in Tekirdag, a couple of hours from Gallipoli, after a police raid of an ISIS cell in Ismaniye, close to the Syrian border, yielded information about the planned attack. The info was gleaned from cellphones and SIM cards.
The threat came after Turkey banned Turkish citizens from attending the Anzac Day service on April 25 due to security concerns and after Turkish authorities arrested four Syrians on April 16 and another suspected ISIS member on April 18.
Commemoration activities were scheduled for both Wednesday and Thursday.
“This is a matter for the Turkish Authorities,” the defense force said in a statement.
One guide said the company he worked for fielded a number of cancellations from people who said they were worried about security.
He said he'd attended the service for the past 22 years but wouldn’t this year. “It is sad. This is my place, this is my life,” he said.
Turkey has said ISIS was responsible for several bombings that took place in 2015 and 2016, which in total killed some 200 people. Although the terrorist group has not been active in Turkey of late, authorities still carry out routine operations against suspected ISIS members.
This year’s ANZAC service comes a month after Turkish President Tayyip Erdogan faced criticism from Australia and New Zealand for comments he made after a lone gunman killed 50 people in two mosques in the city of Christchurch on March 15.
Erdogan played a video from the shootings at local election rallies and said the gunman had targeted Turkey by saying in a manifesto posted online that Turks should be removed from the European half of Istanbul.
He also threatened to send back in coffins anyone who tried to take the battle to Istanbul.
Australian Brenton Tarrant, 28, a suspected white supremacist, has been charged with 50 counts of murder for New Zealand’s worst peacetime mass shooting. Fifty other people were injured in the attacks.
