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.

Participants in a Mine Training Course held at a mock-up minefield staged at Shams Camp near Cairo are seen listening on the signals of an electro- magnetic metal detector. The training course, organized by the Polish Logistic Team, was for Engineering Officers from all UNEF contingents as well as logistic teams to learn about the various types of mines used by Egyptian and Israeli Armed Forces.
