As agreed, the withdrawal was "front-loaded", with half of the Soviet force leaving by August. The withdrawal was complicated, however, by the rapid deterioration of the situation in
Afghanistan. While the
United States was not bound by any commitment to stop arms shipments and continued to supply the
Afghan mujahideen in
Pakistan, the latter was not delivering on its commitment to prevent weaponry and militants from flowing into Afghanistan through the
Durand Line. Likewise, the mujahedeen also continued their attacks on withdrawing Soviet forces.

Soviet Union repeatedly reported these violations of the
Geneva Accords to
United Nations monitoring bodies, and even pleaded with the United States to influence the factions that they were supplying. The desire of the Soviet Union to withdraw, however, coupled with the United States' inability to control the behaviour of the mujahedeen, meant that the Soviet objections did not yield any results.
