In Egypt, a multiple-car crash set off an explosion that ignited a fire at the country’s main cancer hospital and caused 19 deaths.

The health ministry said 30 others were injured by the crash near Cairo’s famed Tahrir Square late Sunday.

The Interior Ministry said in a statement that a vehicle driving outside the National Cancer Institute collided with up to three other vehicles, causing the explosion.

The blast caused a fire in the hospital, where at least 54 patients were evacuated to other hospitals.

The fire was later brought under control, with television footage Monday morning showing shattered windows and doors.

The health ministry did not say if hospital patients or staff were among the casualties.

Why the crash caused such a large explosion wasn’t immediately clear.
