Eight tons of food and medicine were airlifted by India into this capital, which is surrounded by Moslem rebels trying to overthrow the Afghan government, a Foreign Ministry spokesman said Friday.

Rebels meanwhile destroyed a bridge on the main highway linking Kabul to the strategic eastern city of Jalalabad, the government said Thursday.The anti-government forces have pressed in on Jalalabad in an effort to bring about a quick demise of Kabul's Marxist government in the wake of the Soviet troop withdrawal.

The Afghan capital is surrounded by rebels trying to oust the government of President Najib, and convoys carrying supplies into this city of 2.25 million people are occassionally attacked or delayed.

The Indian supplies were flown in Thursday, said the spokesman, who cannot be identified under briefing rules. Another shipment of nine tons of supplies is being readied, the spokesman said from New Delhi.
