Search and rescue operations at the site of the Morandi bridge collapse in Genoa will continue for days, according to an engineer with Italy’s fire department.

"Our work will continue for days," Emanuele Gissi told Italian state broadcaster RAI News 24 during a televised interview.

Gissi also said several people are still missing, based on the number of vehicles on the bridge when it collapsed. He wouldn’t say how many people they were looking for.

A spokesperson for Italy’s civil protection agency told CNN on Tuesday that there were between 25 and 30 cars on the bridge when it collapsed, as well as three to four trucks.

Search and rescue operations will continue through the night, the spokesperson said.
