Japan earthquake sparks tsunami warning
An earthquake with a preliminary magnitude of 7.3 has struck off the coast of Fukushima in Japan.
A tsunami warning for waves of up to three metres (10 feet) was issued.
The Japan Meteorological Agency said the quake struck at a depth of 10 kilometres (six miles). It warned people along the coast to move to higher ground.
Fukushima is north of Tokyo and home to the nuclear power plant that was destroyed by a huge tsunami following an offshore earthquake in 2011.
There were no immediate reports of damage or injury.
