Afghanistan Earthquake: At least 1,000 killed as rescue efforts underway

A powerful earthquake struck eastern Afghanistan, killing at least 1,000 people and injuring 1,500 more. These numbers are expected to rise as rescuers rush to the rural, mountainous region by helicopter. Tremors were also felt across Pakistan and India. The disaster poses a major test for the Taliban-led government, which seized power last year as U.S. troops withdrew.
