North Korea fired two "unidentified projectiles" on Saturday from the northeastern city of Hamhung in the direction of the Sea of ​​Japan. For less than two weeks, shooting series have intensified, fueling tensions between the United States and North Korea.

North Korea fired two "unidentified projectiles" on Saturday, the South Korean agency Yonhap announced, while US-South Korean military exercises denounced by Pyongyang and criticized by Donald Trump started on Monday.

The new "projectiles" have been fired from around the northeastern city of Hamhung in the direction of the Sea of ​​Japan, Yonhap said. "The army is monitoring the situation in case other launches take place and is ready," the South Korean staff quoted the agency as saying.

An obstacle to the resumption of discussions with the United States

This is the fifth round of shooting in less than two weeks by North Korea. It came a few hours after US President Donald Trump claimed to have received a "superb letter" from North Korean leader Kim Jong Un, exposing the recent shootings as retaliation for US-South Korean annual military exercises.

These exercises are considered by the North as a preparation for a possible invasion of its territory and as an obstacle to the announced resumption of discussions with the United States on the denuclearization of the reclusive country. "He was not happy about the military maneuvers," the US president said. "You know I have never loved them either," he added, once again emphasizing his personal goodwill with Kim Jong Un, whom he has met three times since June 2018.
