A candlelight vigil was held on Thursday in the Thai village of Ban Nam Khem to mark 20 years since the massive Indian Ocean tsunami hit the region in one of modern history’s worst natural disasters.

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.

Survivors and relatives of victims of the Boxing Day Tsunami held memorials in Thailand to mark the disaster’s 20th anniversary today. Families laid flowers and lit candles in Phuket and Phang Nga provinces on the east coast of the country,
