Police in the Dutch city of Rotterdam have arrested two men in connection with recent terrorist attacks carried out by Daesh terrorists in Brussels and Paris.

Aged 30 and 32, they are suspected of providing ammunition to a terrorist organization, according to a statement released by the state prosecution service on Friday.

Investigators discovered the mens' fingerprints on a bag containing 45 kilograms of ammunition which was found in a Rotterdam flat during anti-terrorism raids in March.

The flat belonged to a French national identified as Anis B, who has since been handed over to France for his suspected role in the deadly attacks in Paris last November, which left 149 people dead.

He is also suspected of involvement in the Brussels bombing attacks on March 22, which killed over 30.
