Tearful mourners across Asia have commemorated the 220,000 people who died two decades ago when a tsunami hit coastlines around the Indian Ocean.

In Thailand, people gathered at a memorial ceremony in Ban Nam Khem, a small fishing village in Phang Nga province that bore the brunt of the devastating wave in the country. The tsunami claimed the lives of over 8,000 people in Thailand. Many remain missing and nearly 400 bodies are unclaimed to this day.
