Tonga: Journalist gives first-hand account of volcano eruption

The eruption of undersea volcano Hunga Tonga–Hunga Haʻapai, and a tsunami wave, blanketed Tonga's islands in volcanic ash. It's posing a serious health risk and contaminating water supplies.

At least three people have died and communications have been crippled. Tonga has only just begun to re-establish global contact after five days cut off from the rest of the world.

Speaking from Tonga's capital, Nuku'alofa, journalist Marian Kupu gives a first-hand account of the moment the volcano erupted.
