An earthquake which killed more than 200 people in Pakistan has created a new island off the country's coast.

The 7.7-magnitude quake struck on Tuesday afternoon at a depth of 20km (13 miles) north-east of Awaran.

People gathered on the beach to see the new island, which is reported to be about 200m (656ft) long, 100m wide and 20m high.

Dr Simon Boxhall, an an oceanographer from the UK, said the event was "extraordinary but not unique".
