Tribhuvan International Airport, the only international airport in Nepal is closed until 6 AM Wednesday for international flights, airport sources told Nepalnews late afternoon. The airport has been closed to repair the damage to the northern end of the runway after an MI 17 army helicopter crashed on the runway Monday.

Earlier reports said the airport would be open for international flights Tuesday evening. Rains today hampered the reconstruction of the damaged runway, airport sources said.

Domestic airlines are operating using half the runway.
