An earthquake with a preliminary magnitude of 5.6 shook Tokyo and surrounding areas on Monday, but no tsunami warning was issued, Reuters quoted Japan Meteorological Agency as saying. The quake was centred in Ibaraki prefecture just northeast of the Japanese capital. There were no immediate reports of damage or injuries, and no reports of abnormalities at any nuclear facilities. The U.S. Geological Survey measured the quake at 5.3 magnitude. The tremor shook buildings in Tokyo and briefly halted some train lines, including the Tokyo Metro subway lines. -- SPA 11:42 LOCAL TIME 08:42 GMT تغريد
