France is facing the fear of deadly attacks after several people were stabbed at a church in the Mediterranean city of Nice, prompting the country to raise its security alert status to the highest level.
This is what we know so far:
A man armed with a 30cm (12 inches) knife began attacking people praying inside the Basilica of Notre-Dame in Nice.
He slit the throat of a 60-year-old woman, and a church worker, and badly wounded another woman.
The 60-year-old woman and the church employee died on the spot, while the other woman, who was 44, managed to make it out of the church into a nearby cafe, but later died from her wounds, Nice Mayor Christian Estrosi told reporters at the scene.
The sexton – a member of staff responsible for the upkeep of the church – was 55.
