French police interrogated one suspect and searched for others on Sunday, after a Greek Orthodox priest was shot and critically wounded while closing the door to his church in the city of Lyon.

Investigators are trying to determine whether a man arrested on Saturday night was the gunman behind the attack, or has information about it, according to a police official.
