WASHINGTON, Feb. 10 - The Group of Seven rich industrial nations and the International Monetary Fund are weighing up a much larger aid package for Ukraine, acknowledging that it is teetering on the edge of bankruptcy, sources familiar with the talks say, Reuters reported.

One source told Reuters the overall package could be swelled to around $40 billion, a sum that would include the existing aid on offer, although discussions are ongoing and nothing has been finalized.
