At least 20 people were killed in four bomb attacks - three of them car bombs - in Morocco's commercial capital Casablanca on Friday night, the official MAP news agency said.
The car bomb attacks targeted the Belgian consulate, a Jewish community centre and the Hotel Safir, located in the old heart of the city centre.
A fourth bomb, which was apparently not in a car, exploded near the Spanish cultural centre.
Three suspects were arrested, the agency said, without giving further details.
