Residents of Pakistan's capital have been jolted from their beds by a 5.3-magnitude earthquake, but there were no injuries or damage reported.
Arif Mahmood, a seismological official in the north-western city of Peshawar, said the quake's epicentre was only about 17 miles north of Islamabad.
It occurred at about 2.45am on Monday and was shallow, at about six miles deep, resulting in strong shaking.
A 7.6-magnitude earthquake that struck on October 8, 2005, killed more than 80,000 people and left three million homeless, devastating areas around the epicentre in Pakistan-held Kashmir, north-west of Islamabad.
It also toppled an apartment block in the capital, killing 74 people.
