Japan puts military on alert for possible North Korean missile test

Meanwhile, the United States has seen increased activity around a North Korean missile site, suggesting preparations for a possible space launch in the near future, U.S. officials told Reuters on Jan. 28. 

The officials cited intelligence suggesting movement of components and propellant at North Korea's Sohae satellite launch facility. A test could take place within a couple of weeks, they said. 

"Our concern though is ... it's the same technology to develop ICBMs [inter-continental ballistic missiles]," one of the officials said. 

"We are keeping a close eye on these activities by the North Koreans. We're watching 24/7," a second official said....
