SWITZERLAND-BELGIUM-BUS-ACCIDENT

This picture taken on March 13, 2013 above Saint-Luc, in the Swiss canton of Valais, shows a commemorative plaque bearing the name of the persons who died in a traffic accident a year ago. A ceremony in memory of the 22 Belgian school children and six adults killed in a horrific bus accident in the Swiss Alps will take place on the one-year anniversary of the tragedy near the accident site. The small town of Sierre in the southern canton of Valais announced on its website on February 21 that it would host the ceremony at 6:00 pm (1700 GMT) on March 13 at the town church, a year after the Belgian bus smashed into the wall of a nearby Alpine tunnel at 100 kilometres (65 miles) an hour.
