Nauru has become the latest country to sign up to the 1949 Geneva Conventions on the protection of civilians and prisoners during war.
The Swiss-based International Committee of the Red Cross, which is the official guardian of the convention, says with Nauru's and Montenegro's signature, the convention has now complete support.
The ICRC says the Geneva Conventions have 194 signatories, marking for the first time in modern history that an international treaty has achieved universal acceptance.
The conventions aim to protect the rights of people not taking part in hostilities -- such as civilians, first aid and religious workers as well as humanitarian organisations -- as well as those not taking part in combat, such as the sick, wounded and prisoners of war.
