President Maumoon Abdul Gayoom of the Maldives was inaugurated Friday for a third five-year term after weathering a coup attempt on the Indian Ocean island chain last week, the government said. "In view of what happened last week, the ceremony was simple. There was no fireworks, no celebrations," said Ahmed Saleem, a Foreign Ministry undersecretary contacted by telephone from New Delhi. Saleem said 1,200 guests, including delegates from the United States and India, attended the ceremony in Male, the Maldivian capital. On Nov. 3, an estimated 150 Sri Lankan mercenaries tried to overthrow the government but fled the next day when hundreds of Indian paratroopers arrived at Gayoom's request.
