A powerful blast in a residential building in the Argentine city of Rosario has killed at least eight people and injured more than 60 others.
Emergency teams have been trying to put out a fire and rescue the people who remain trapped in the upper floors.
Rescue teams say there is a risk of the apartment block collapsing. Nearby buildings have also been affected.
The explosion was probably caused by a gas leak in the building's heating system, local authorities said.
Ignacio de los Reyes reports.
