International aid agencies have begun the biggest relief effort in history to help survivors in 12 countries hit by the massive earthquake in Asia.
More than 50,000 people are feared dead after the quake, measuring 9.0 on the Richter scale, sent huge waves crashing into countries, wiping out communities.
Water, food and medicine are being sent to help thousands of people who have been made homeless by the disaster.
The worst-hit countries are Indonesia, Sri Lanka, India and Thailand.
Somalia, Burma, Malaysia, the Maldives, Tanzania, the Seychelles, Bangladesh and Kenya were also affected.
The UK was preparing to send out tonnes of emergency supplies, including water pumps and tanks and toilet facilities.
There are fears that people in the affected area could get ill through drinking polluted water.
Exact numbers of people killed, injured or missing are difficult to confirm as the rescue effort continues.
