Security forces shot dead a man who seized a soldier’s gun at Paris Orly airport today.
A police officer was shot and injured in a separate incident north of the French capital.
A bomb sweep took place at the airport to make sure the dead man was not wearing an explosive belt, but nothing was found.
The incidents come weeks before France holds Presidential elections.
The country remains on high alert after attacks by ISIS militants killed scores of people in the last two years and a state of emergency is in place until at least the end of July.
Around 3,000 passengers were evacuated from the airport, the second busiest in the country.
