North Korean leader Kim Jong Un offered “a small apology” for the ongoing missile tests — and said they were in retaliation for the joint military exercises that American and South Korean forces have mounted, President Trump tweeted Saturday.

“In a letter to me sent by Kim Jong Un, he stated, very nicely, that he would like to meet and start negotiations as soon as the joint U.S./South Korea joint exercise are over,” Trump tweeted.

“It was also a small apology for testing the short-range missiles, and that this testing would stop when the exercises end,” he wrote.

Trump has vocally opposed the military practice sessions, saying they are unnecessary and expensive.

North Korea sent two more short-range missiles into the Sea of Japan Saturday, just hours after President Trump said he received a “very beautiful letter” from its leader, Kim Jong Un, and hinted another meeting between them could be in the works.

South Korean officials called the latest missile launches a “show of force” intended to make a statement during U.S.-South Korea joint military exercises, Reuters reported.

It’s “highly probable,” there will be more rockets fired, South Korea’s Joint Chiefs of Staff said in a statement, because the North Korean military is conducting its own summer drills.

The rogue nation has fired five rounds of missiles in less than three weeks, and may also be protesting the slow pace of denuclearization talks that were supposed to restart after Trump and Kim met in Vietnam on June 30.

The two missiles fired Saturday flew about 250 miles, according to the South Korean military.
