MASHIKI, Japan, Rajab 09, 1437, April 16, 2016, SPA -- A powerful earthquake with a preliminary magnitude of 7.3 struck southern Japan early Saturday, barely 24 hours after a smaller quake hit the same region and killed nine people, according to AP. While it was not immediately clear whether the latest quake increased the death toll, authorities said hundreds of calls had come in from residents reporting people trapped inside houses and buildings. The Fire and Disaster Management Agency said 66 people were trapped inside a nursing home in Mashiki, the hardest-hit town, and rescue efforts were underway. No other details were immediately available. --SPA 02:22 LOCAL TIME 23:22 GMT www.spa.gov.sa/w
