MOMBASA, Kenya, Ramadan 20, 1436, Jul 7, 2015, SPA -- Al Shabaab militants killed 14 people, mostly quarry workers in an overnight attack on a residential complex in northeast Kenya Reuters cited officials as saying. Many died in their sleep, the Kenya Red Cross said. The raid, in the town of Mandera, mirrored one in the same county in December in which 36 quarry workers died. Al Shabaab says will continue its attacks until Nairobi withdraws its troops from an African Union force fighting the militants in their home base of Somalia. The group's military operations spokesman, Sheikh Abdiasis Abu Musab, told Reuters its group holds responsibility for the assault. --SPA 13:19 LOCAL TIME 10:19 GMT www.spa.gov.sa/w
