A Greek Orthodox priest has been seriously wounded in a shooting in the French city of Lyon on Saturday, officials say.

The incident came days after three people were killed in a knife attack at a church in the southern city of Nice.

French President Emmanuel Macron called the killings an “Islamist terrorist attack” and deployed thousands of extra soldiers to protect public sites, including places of worship.

In Lyon, the gunman fled the scene, sparking a manhunt.

Authorities have opened an investigation of attempted murder.

A suspect resembling witness descriptions was later taken into custody, but has since been released. The prosecutor’s office said it found no evidence of the man’s involvement, suggesting the gunman could still be at large.
