An Israir plane was impounded in Lisbon Monday over an alleged debt of millions of euros owed by the company to EuroAtlantic Airways, a Portuguese carrier, according to the Times of Israel.

Dozens of Israeli passengers of the airline were stranded in Lisbon after their return flight to Tel Aviv was canceled, according to a report on Ynet. A Portuguese news report said that the plane landed in Lisbon at 10:30 a.m. Monday with Israeli passengers and was set to return to Israel the same day.
