Indonesia and Thailand are marking 20 years since a tsunami caused the death of hundreds of thousands of people in one of the worst natural disasters in modern history.
People started gathering in prayer today and visiting mass graves in Aceh, one of the worst-hit areas by the Boxing Day Indian Ocean tsunami which killed an estimated 230,000 people across a dozen countries.
The tsunami was triggered by a 9.1-magnitude earthquake that struck off the west coast of North Sumatra, Indonesia, at 7.59am local time on 26 December 2004.
Indonesia suffered the highest number of deaths, but India, Sri Lanka and Thailand were also badly hit.
Many wept openly at the mass grave in Ulee Lheue village, where more than 14,000 unidentified and unclaimed tsunami victims are buried. It is one of several mass graves in Banda Aceh, the capital of Indonesia’s northernmost province.
Footage showed people visiting a mass grave in Siron to remember the victims of an event that shocked the world.
People gather to mark the anniversary in Thailand
In Thailand, people gathered in Phang Nga province to honour the victims and those affected.
Survivors and relatives of tsunami victims in Sri Lanka gathered at the coastal village of Pereliya and laid flowers at a memorial commemorating nearly 2,000 passengers who died when their train, the Queen of the Sea, was hit by the wave. Just a few dozen people are believed to have survived.

Sir Keir Starmer said his thoughts are with the “millions of people who were affected” by the tsunami.
In a post on X, the prime minister said: “Today marks 20 years since the devastating Indian Ocean tsunami that took the lives of so many.
“My thoughts are with those who lost loved ones and the millions of people who were affected by the disaster, as well as all those who helped with the recovery.”

In Aceh, the tsunami reached 167ft (51m) high, according to the United Nations Office for Disaster Risk Reduction (UNDRR) and caused flooding up to three miles (5km) inland.
The infrastructure in Aceh has been rebuilt and is now more resilient than 20 years ago.
Early warning systems have been installed in coastal areas to alert residents of potential tsunamis, providing crucial time to seek safety.
The rebuilding efforts were made possible by the support of international donors and organisations, who contributed significant funds to help the region recover.
Schools, hospitals, and essential infrastructure that were destroyed by the disaster have been reconstructed with enhanced strength and durability, ensuring better preparedness for future challenges.

Various communities in Aceh commemorate the tsunami yearly along with the government and local authorities.
In Banda Aceh, art communities in early December spread disaster awareness through theatrical or musical performances that can be easier for people to follow and target all groups, including those born after the tsunami.
