Reagan to Moscow: seek an Afghanistan solution

President Reagan, marking the third anniversary of Soviet intervention in Afghanistan, said Sunday the occupation was not a success and urged Moscow's new leaders to work toward a peaceful solution.

In a statement, the President said even with forces numbering almost 105,000, the Soviet Union had been unable to control the countryside or secure many cities and had failed to rebuild the communist-controlled Afghan Army or create an effective government. ''This is due to the spirit and will of the majority of the Afghan people and to the mujahedin, the freedom fighters, who continue to resist the Soviet invaders,'' Reagan said.
