Cargo planes flew into Sarajevo Tuesday after Bosnian Serbs promised to stop shelling the airport, but the operation shut down again after a new attack. Shelling elsewhere in the city killed six people.
U.N. troops closed the airport when a shell hit the runway after about half of a planned 23 planes had arrived with badly needed food and medicine. The airport reopened within an hour after repairs, but it was unclear whether aid flights - which have been suspended most of the past week - would resume.U.N. officials said it was unclear who fired the mortar round, which hit after Serb troops besieging Sarajevo resumed artillery attacks on the capital's downtown in the morning.
The airport attacks underlined how much U.N. aid efforts are dependent on the good will of Bosnia's three warring factions. Western threats to use force against those interfering with aid shipments have largely been ignored.

The Croatian government denied owing the money.
