SEOUL, April 01. /ITAR-TASS/. North Korea (DPRK) is preparing for missile launches, to which a ban on the passage of ships, imposed by the North, testifies, South Korea’s Yonhap news agency reported on Tuesday.

“North Korea has internally set the no-sail zone in waters near Wonsan this week to control its vessels,” the agency quotes a South Korean military source who spoke on condition of anonymity. “It is highly likely that the North may fire ballistic missiles.” Wonsan is located on the south-eastern coast, where missile and rocket launches have taken place in recent weeks.

However, according to official Seoul, no preparations for another underground nuclear test are so far being observed in North Korea.

Last week, Pyongyang carried out two launches of the medium-range ballistic missiles of the Rodong type, which was denounced by the UN Security Council.

According to South Korean media, North Korea in the period from February 21 to March 31, has launched a total about 600 various missiles, also firing volley fire rocket system rounds.
