French Prime Minister Jean-Pierre Raffarin has successfully undergone gall bladder surgery.

Defense ministry officials say the surgery Saturday went well and they indicate that Mr. Raffarin will remain in the hospital for several days.

Earlier Saturday, Mr. Raffarin abruptly canceled plans to travel to World War II anniversary ceremonies in the city of Reims. Instead, he entered the Paris Val De Grace military hospital.

The 56-year-old Mr. Raffarin assumed the post of prime minister three years ago.
