Seoul, South Korea, Rajab 10, 1434, May 20, 2013, SPA - North Korea on Monday fired a projectile into the sea off its east coast, the fifth in three days, South Korea said. The South Korean Defense Ministry still needs to analyze exactly what the North fired, said Choi Yong-su, an official in the ministry's spokesperson's office. The projectiles the North Korea launched over the weekend could be short-range missiles or a new kind of large-caliber artillery, the defense ministry said earlier Monday, according to a report of CNN. --SPA 11:45 LOCAL TIME 08:45 GMT www.spa.gov.sa/1112034
