France's president has raised the possibility of Greece leaving the shared euro currency, but says that's a decision for "Greece alone" to make.

Some in Europe have expressed concern that if the left-wing Syriza party wins this month's general election in Greece, the new government may renege on terms of a hugely expensive international bailout plan. That has revived questions about Greece's fitness to stay in the euro.

Francois Hollande said on France-Inter radio Monday that Greece's new leaders "will have to respect the commitments made by their country."

But he insisted that it's not up to others to say whether the result of the Greek vote means they should or shouldn't keep using the euro currency.

That, he said, "is for Greece alone to decide."
