PYONGYANG, May 2 (Xinhua) -- The Democratic People's Republic of Korea (DPRK) said Tuesday that the U.S. military Monday conducted in South Korea a nuclear bomb dropping drill on targets of DPRK in South Korea, calling it an "extremely reckless" move for nuclear war on the Korean peninsula.

"On May 1, the U.S. imperialists committed one more military provocation of conducting a nuclear bomb dropping drill against the major objects of the DPRK in the sky over South Korea by bringing a formation of notorious nuclear strategic bomb B-1B in the wake of Key Resolve and Foal Eagle 17 joint military drills," said the Korean Central News Agency.

The report said the bombers took off from the Guam and "stealthily came in the sky over the East Sea of Korea in order to acquire the procedure and way of the coordinated operation with the strategic striking means such as nuclear carrier and nuclear sub."

"What merits a serious attention is that such a military game is underway when (U.S. President Donald) Trump and other U.S. warmongers are crying out for making a preemptive nuclear strike at the DPRK day after day," it said.

Tension has remained very high over the past two months between the United States and the DPRK over the former's threat to stage military attack upon Pyongyang for its nuclear and missile programs.

The United States and South Korea also held their largest ever joint military exercises in the past two months, while the USS Carl Vinson nuclear aircraft carrier task group has arrived in the waters off the peninsula for joint drills with the South Korean military.
