Monaco’s Government on Friday ordered that all flags on state properties be lowered to half-mast on Saturday, August 18, in solidarity with Italy’s day or mourning for the victims of the Genoa bridge collapse.

The port city lies just two hours away by car from Monaco and there are strong links on every level between the Principality and Italy’s sixth-largest town. Monaco’s history is also closely linked to that of Genoa, the original birthplace of the Grimaldi dynasty.

The official death toll from the collapse of the Morandi viaduct arose to 43 on Saturday, when the search for bodies ended. Four victims remain in hospital in critical condition.
