Guerrillas fired rockets into the capital of Afghanistan Thursday, causing heavy damage to Kabul airport and parts of the city, diplomatic sources and the Tass news agency said.

Western diplomats, quoting dispatches from Kabul, said one explosion at the airport sent smoke billowing 3,000 feet into the air. They said it indicated an ammunition dump had blown up.Earlier Thursday, the Foreign Ministry said Afghan warplanes bombed villages about 40 miles inside Pakistan, killing one person and prompting a protest from the government.

"It caused massive damage judging by the smoke," one diplomatic source said. The sources spoke on condition of anonymity.
