North Korea criticized the United States for pursuing the "absurd and outdated" goal of denuclearization Tuesday, saying that Pyongyang would stick to leader Kim Jong Un's goal of building up its nuclear forces.

North Korea on Wednesday rejected US President Donald Trump's proposal to "take over" the Gaza Strip and relocate Palestinians to other countries, calling it an "act of forcibly expelling the Gazan people."

North Korea's foreign ministry said on Tuesday that it will keep bolstering its nuclear force, denouncing a recent joint pledge by the United States, South Korea and Japan for its denuclearisation, according to state media KCNA.

South Korea has deployed a new homegrown bunker buster missile, the Joint Chiefs of Staff (JCS) said Tuesday, in its efforts to deter North Korean military threats.
