The government Friday condemned Thursday's terrorist attacks in the southern French city of Nice which killed at least 80 people and wounded hundreds of others.

"If it is a terrorist attack, it is utterly intolerable," Prime Minister Shinzo Abe said at the Asia-Europe Meeting held in the Mongolian capital of Ulan Bator.

"It was a cruel attack and I offer my sincere condolences to the victims," Abe said. "Japan expresses its strong solidarity with France at this difficult time."
