The North Korean government has moved two short-range missile launchers to the nation's east coast, Reuters reported on Saturday.

The incident raises questions of whether North Korean leader Kim Jong-un is proceeding with anticipated plans to fire a missile on April 25, the anniversary of the founding of the Korean People's Army.

"The military is closely watching the North's latest preparations for a missile launch," a source told South Korea's Yonhap news agency.

Yonhap was the first to report on North Korea moving the missile launchers, after determining from satellite imaging photos that two mobile short-range Scud missiles had been moved into South Hamgyeong province.

Earlier this month, Joint Chiefs of Staff chairman, U.S. Gen. Martin Dempsey, told Fox News, that although he believes the escalating rhetoric coming out of North Korea will not amount to anything, "I can't take the chance that it won't."

Dempsey said the U.S. government is "considering the risk [the North Korean government] may choose to do something" on April 25, the anniversary of the founding of the Korean People's Army.

April 15, the birth of North Korean founder Kim Il Sung, was also considered a potential attack date.

Kim Min-seok, South Korean defense ministry spokesman told UK publication the Telegraph that his country's military is also preparing for a possible attack on April 30--the final day of ongoing South Korea-U.S. military exercises.

Now that April 15 has passed without incident, Min-seok also cautions that the July 27 anniversary of the armistice that ended the Korean War in 1953 is one more possible missile launch date this year.

"These are three potential dates...but no one can predict exactly what direction the North will take," he said.

The predicted North Korean missile firing is expected to test a Musudan missile. With a firing range of up to 2,500 miles, the missile could easily reach South Korea and Japan and potentially hit US military bases on the Pacific island of Guam.
