Chile quake: 7.6 tremor among 100 aftershocks

A powerful 7.6 magnitude earthquake has rocked northern Chile, just over 24 hours after an 8.2 tremor killed six people.

President Michelle Bachelet was visiting the northern city of Arica to assess the damage, when the aftershock struck and she was forced to leave her hotel.

A tsunami alert was again issued, but was later lifted after waves of 2.4ft (0.7 meters) hit coastal areas.

The BBC's Ignacio De Los Reyes said the huge tremor was one of "100 aftershocks" to hit the region since Tuesday.
