US B-1B Bomber Flies over Korean Peninsula during Military Drills

The bomber flew from Guam and joined US F-22 and F-35 stealth fighters in the exercises with South Korea. The drills, which kicked off on Monday and will run until Friday, are being conducted at a time of heightened tensions on the peninsula.

They also come after North Korea tested last week what it called its most advanced intercontinental ballistic missile (ICBM) that could reach all of the United States.

North Korea regularly threatens South Korea, the United States and their allies, and its official KCNA state news agency said at the weekend US President Donald Trump’s administration was "begging for nuclear war” by staging the drills.

It also labeled Trump as "insane”.

The drills also coincided with a rare visit to the isolated North by United Nations political affairs chief Jeffrey Feltman.

Some analysts and diplomats hope Feltman’s visit to North Korea could spark a UN-led effort to defuse rising international tensions over Pyongyang’s nuclear and missile programs.

North Korea’s state media confirmed the arrival of Feltman and his entourage late on Tuesday without offering more details, later issuing a photograph of him and two members of his team.

Feltman, a former senior US State Department official, is the highest-level UN official to visit North Korea since 2012. The US State Department said on Tuesday he was not carrying any message from Washington during his visit, Reuters reported.

South Korean President Moon Jae-in will visit China next Wednesday for a summit with his counterpart Xi Jinping, Seoul’s presidential Blue House said on Wednesday. North Korea’s increasing nuclear and missile capability would top the agenda, it said.

Moon will also meet Chinese Premier Li Keqiang during his four-day trip and visit Chongqing, Blue House spokesman Park Soo-hyun told a news briefing.

Chongqing was home to Korea’s government-in-exile during Japanese rule from 1910-45 and is now an industrial hub of Xi’s "One Belt, One Road” initiative for infrastructure development.

Moon has described the North’s latest ICBM as their most capable yet, although it has several critical points to prove, such as re-entry technology and terminal stage guidance.

The annual exercise, called "Vigilant Ace”, is designed to enhance joint readiness and operational capability of US extended deterrence, South Korea’s Joint Chiefs of Staff said in a statement.

Around 12,000 US service members, including from the Marines and Navy, are joining South Korean troops, while aircraft are flying from eight US and South Korean military installations, officials have said.

The US Air Force has said the size of this year’s drill is "comparable” to previous years.

North Korea has vehemently criticized the drills since the weekend, saying the exercise precipitates US and South Korean "self-destruction”.

China and Russia had proposed that the United States and South Korea stop major military exercises in exchange for North Korea halting its weapons programs. Beijing formally calls the idea the "dual suspension” proposal.

Russia also has communication channels open with North Korea and Moscow is ready to exert its influence on Pyongyang, the RIA news agency quoted Russian Deputy Foreign Minister Igor Morgulov as saying on Tuesday.
