President Zia ul-Haq on Saturday accused the Soviet Union of sending thousands of troops back into Afghanistan to defend the capital of Kabul, but Moscow called it a "sheer lie" and said its pullout is continuing.

The official Soviet news agency Tass reported meanwhile that Afghan rebels fired six rockets into residential areas of Kabul Saturday, killing two people, including a 3-year-old girl. Tass said six people were wounded and several homes destroyed in the third rocket attack on Kabul in a week.Zia, the Pakistani army chief of staff, said the Soviets "decided not only to stop their withdrawal but they have also brought in something like 10,000 troops back from the Soviet Union into Kabul because Kabul was under threat."
