VYSNE NEMECKE, Slovakia (Reuters) - When Russia invaded Ukraine last week French professor Yves Gineste didn't think twice - he set off on a four-day drive to the eastern edge of Slovakia to offer his Perpignan house to refugees.
Bearing a cardboard sign seeking "One family for a house in France, travel and house free", he registered with a charity at Vysne Nemecke, a crossing on the Slovakia-Ukraine border.
