Jakarta - Indonesia Friday marked the fourth anniversary of the Boxing Day tsunami, with thousands of people scrambling up to higher ground on the coast of North Sulawesi as sirens blared in a drill.
In Aceh at the northern end of Sumatra, where more than 170,000 people were either killed or went missing when a massive 9.0-magnitude earthquake triggered a tsunami on December 26, 2004, hundreds of survivors prayed at mosques across the staunchly Muslim province, the state-run Antara news agency reported.
Hundreds of others prayed at mass graves or gathered along the Aceh coast to honour victims of the 2004 Indian Ocean tsunami that claimed up to 230,000 lives in 11 countries and displaced more than 1.8 million people.
