BARDONNEX, Switzerland (Reuters) - Thousands of French workers were stuck in traffic on Tuesday as Switzerland tightened border controls under new emergency measures to curb the spread of the coronavirus.

Only Swiss citizens, residents and people travelling for business can enter Switzerland under the new regime, which also affects Germany, France and Austria. The Swiss had already tightened monitoring of cross-border traffic from Italy.
