SAN JUAN, Puerto Rico — Repair crews worked through the night trying to restore electricity to Puerto Rico's 3.5 million people early Thursday after a fire at a power plant blacked out the entire U.S. territory.
Officials said they hoped to restore service by morning, but some schools canceled classes for the day as a precaution. The island's largest public hospital canceled elective surgeries and non-urgent appointments, while government officials and private groups put off dozens of scheduled events.
