Budget airline Avianova, which has been embroiled in a bitter shareholder dispute between its U.S. and Russian partners, has stopped all flights and will file for bankruptcy.
The venture, set up in 2009, descended into acrimony in June when a number of executives were physically denied access to Avianova's Moscow offices.
In an official statement late Sunday, the airline said it was ceasing all flights because U.S.-based Indigo Partners had halted funding for the project. Indigo Partners said in a statement that Avianova would file for bankruptcy.
Avianova is 49 percent held by Indigo Partners and 51 percent by A1, the investment arm of Mikhail Fridman's Alfa Group.
