New Zealand quake: Christchurch hit by aftershocks

A series of tremors has hit the New Zealand city of Christchurch, almost four months after an earthquake devastated the area and killed 181 people.

The quakes struck a few miles from the city, leaving some 50,000 people without power or water.

Christchurch airport, shopping centres and office blocks were evacuated as the quakes hit.
