New Zealanders are among those allegedly targeted by a foiled Anzac attack at Gallipoli

The New Zealand Defence Force says the Anzac Day commemorations in Gallipoli are going ahead, despite Turkish media reporting an alleged terror plot to attack the service.

A suspected Islamic State member was arrested in Turkey over a plot to attack today's commemorations, which will be attended by hundreds of New Zealanders and Australians.

Kiwis in Gallipoli have reported extremely tight security conditions, including a two-hour wait to get through security checkpoints to reach the peninsula at Anzac Cove.

Australian media reported the suspect was planning to bomb the service or drive a car into the crowd, in retaliation for the Christchurch mosque attacks.
