Japan marks earthquake and tsunami anniversary

Services have been held in Japan to mark the devastating earthquake and tsunami that struck two years ago.

Ceremonies took place in the three worst-hit prefectures and a minute's silence was observed at 14:46 (05:46 GMT), when the quake hit.

More than 18,000 people were left dead or missing in the disaster, which also caused the Fukushima nuclear crisis.

The BBC's Rupert Wingfield-Hayes says little re-building has been done in the worst-hit areas.
