account the observation in his report describing the problems encountered
by the Force in carrying out its mandate,

and 426 (1978),

co-operate fully and urgently with the United Nations in the
implementation of Security Council resolutions 425 (1978) and 426

Council in two months on the implementatiuoin of the present resolution
