Coffins are displayed during a remembrance service at the Soeverein hall in Lommel on March 21 for the 28 victims of last week's fatal school bus crash in a Swiss alpine tunnel. Belgium's king and the Dutch crown prince joined thousands of mourners in a highly emotional homage in the sleepy northern town near the Dutch border, home to 17 of the dead, six of them Dutch nationals. Swiss investigators are due to travel to Belgium soon to question the children on board the coach in attempts to ascertain the cause of the accident.
