Damaged roads and bridges, power blackouts and lack of heavy equipment on Saturday hampered Indonesia's rescuers after a 6.2 magnitude earthquake left at least 45 dead and hundreds injured on Sulawesi island.

Axar.az reports citing foreign media that operations were focused on about eight locations in the hardest-hit city of Mamuju, where people are still believed trapped following Friday's nighttime quake, said Saidar Rahmanjaya, who heads the local search and rescue agency.

Cargo planes carrying food, tents, blankets and other supplies from Jakarta landed late Friday for distribution in temporary shelters. Still, thousands spent the night in the open fearing aftershocks and a possible tsunami.
