Deadly quake rocks New Zealand, topples buildings

Christchurch, February 22, 2011 (Agencies): A powerful earthquake struck one of New Zealand's biggest cities Tuesday at the height of a busy workday, toppling tall buildings and churches, crushing buses and killing at least 65 people in one of the country's worst natural disasters.

It was the second major quake to hit Christchurch, a city of 350,000, in five months, though Tuesday's 6.3-magnitude temblor caused far more destruction than a more powerful September quake that struck before dawn on a weekend.
