Prime Minister David Cameron has pledged his support to the people of Indonesia after an earthquake and a powerful aftershock rocked the country's south west coast just hours after he arrived.
A tsunami warning has been issued for the entire Indian Ocean, although there's no sign of one being generated after the quake - which measured 8.6 on the Richter scale - happened 20 miles under the sea bed 300 miles off Aceh Province. The aftershock measured 8.2.
Chaos ensued on the streets of Aceh as countless people fled from their coastal homes in cars and on motorbikes over fears of a repeat of the tsunami in 2004, where 170,000 people died. Parents have been rushing their children to hospital, but at the moment no deaths have been reported and the damage appears to be minimal.
Here distraught and frightened families gathered both inside and outside a mosque for the latest news.
Meanwhile hospitals in Thailand were being evacuated as the country's National Disaster Warning Centre ordered residents living in six provinces across the country's west coast - including tourist destinations like Phuket and Krabi - to leave.
The Prime Minister is on a mission to strengthen trade and investment between the nations, and - speaking at a joint press conference with the President - he offered support to Indonesia, should the country need it.
