France's health minister says about 85 people remain hospitalized after a deadly truck rampage in the Mediterranean city of Nice, and 18 of them are in life-threatening condition — including one child.

Health Minister Marisol Touraine urged any survivors to seek counseling offered by the government after the Bastille Day attack Thursday night that killed 84 people.

Speaking to reporters in Nice on Sunday, Touraine said while scores of people who were hospitalized have been released, some may need further medical treatment as their injuries heal.

The Islamic State group has claimed responsibility for the attack by a local Nice truck driver who was killed by police.
