On 6 October 1973 hostilities broke out again in the Middle East. The Security Council held several urgent meetings and on 22 October called for a cease-fire. Three days later, on 25 October, it decided to send a 7,000-man U.N. Emergency Force (UNEF) to the area to observe the cease-fire and to do its best to prevent a recurrence of the fighting.

German shepherd dogs of the Swedish Battalion with UNEF are seen at a mock-up minefield staged at Shams Camp near Cairo where the dogs showed their ability to sniff mines at a Mine Training Course organized by the Polish Logistic Team. Engineering Officers from all UNEF contingents as well as logistic teams participated in the Course to learn about various types of Egyptian and Israeli mines.
