More than 60 people have been killed in the Philippines after a 6.9-magnitude earthquake collapsed houses and nightclubs.

The magnitude-6.9 earthquake struck at about 10pm local time on Tuesday (3pm BST), leaving an unspecified number of residents trapped in collapsed homes, nightclubs and other businesses in the hard-hit city of Bogo and outlying rural towns in Cebu province, officials said.

Rescuers scrambled to find survivors on Wednesday. Army troops, police and civilian volunteers backed by digging equipment and sniffer dogs were deployed to carry out house-to-house searches for survivors.

The epicentre of the earthquake, which was set off by movement in an undersea fault line at a dangerously shallow depth of three miles, was about 12 miles north-east of Bogo, a coastal city of about 90,000 people in Cebu province, where about half of the deaths were reported, officials said.

The death toll in Bogo was expected to rise, according to officials, who said intermittent rain and damaged bridges and roads were hampering the race to save lives.
