At least 40 people are dead after a bus plunged off a bridge on the outskirts of Guatemala’s capital.

Fire service spokesman Edwin Villagran said a multi-vehicle crash sent the bus off the bridge before dawn.

Another 15 people were seriously injured.

The bus had come from Progreso, north-east of the capital, Guatemala City.

Volunteer firefighting spokesman Oscar Sanchez said children were among the victims.

President Bernardo Arevalo offered his condolences and declared a day of national mourning.
