France's transport chief is threatening to force striking train drivers back to work to ensure transport for fans attending the European Championship soccer tournament starting Friday.

Unions are targeting the commuter train lines serving the national stadium hosting the opening match Friday, as part of nationwide strikes over labor conditions in recent weeks.

Alain Vidalies, junior minister for transport, insisted that transport to the opening match would be ensured.

But asked if the government would use special measures to force train drivers back to work for reasons of public order, Vidalies said Friday on Europe-1 radio that if transport problems worsen Saturday, "we will do it."

Garbage collectors are also on strike in some areas and Air France pilots are going on strike starting Saturday.
