North Korea fires missiles into the sea

Three North Korean short-range ballistic missiles failed on Saturday, US military officials said, which, if true, would be a temporary setback to Pyongyang's rapid nuclear and missile expansion.

The US Pacific Command said in a statement that two of the North's missiles failed in flight after an unspecified distance, and another appeared to have blown up immediately. It added that the missile posed no threat to the US territory of Guam, which the North had previously warned it would fire missiles toward.

Seoul's Joint Chiefs of Staff said that the projectiles fired from the North's eastern coast flew about 250 kilometers (155 miles), though it did not mention any failures. It said South Korea and US militaries were analysing the launch and didn't immediately provide more details.

South Korea's presidential office held a National Security Council meeting to discuss the missiles, which are the first known launches since July, when the North successfully flight tested a pair of intercontinental ballistic missiles that analysts say could reach deep into the US mainland when perfected.

The White House said that President Donald Trump — who has warned that he would unleash "fire and fury" if the North continued its threats — was briefed on the latest North Korean activity and "we are monitoring the situation."

The rival Koreas recently saw their always testy relationship get worse after Trump traded warlike threats. The latest launch comes during an annual joint military exercise between the United States and South Korea that the North condemns as an invasion rehearsal, and weeks after Pyongyang threatened to lob missiles toward Guam.

North Korea had walked back from the threat to lob missiles toward Guam, but there had been concerns that hostility will flare up again during the Ulchi-Freedom Guardian drills between the allies that run through Aug. 31.

However, some experts say North Korea is now mainly focused on the bigger picture of testing its bargaining power against the United States with its new long-range missiles and likely has no interest in letting things get too tense during the drills. They say the North may limit its reactions to low-level provocations like artillery and short-range missile launches.

North Korea's state media earlier on Saturday said that leader Kim Jong Un inspected a special operation forces training of the country's army that simulated attacks on South Korean islands along the countries' western sea border in what appeared to be in response to the ongoing US-South Korea war games.

Kim reportedly told his troops that they "should think of mercilessly wiping out the enemy with arms only and occupying Seoul at one go and the southern half of Korea."

The Korean Central News Agency said that the "target striking contest" involved warplanes, multiple-rocket launchers and self-propelled guns that attacked targets meant to represent South Korea's Baengnyeong and Yeonpyeong islands before special operation combatants "landed by surprise" on rubber boats.

The border islands have occasionally seen military skirmishes between the rivals, including a North Korean artillery barrage on Yeonpyeong in 2010 that left two South Korean marines and two civilians dead.

In response to North Korea's expanding nuclear weapons programme, South Korea has been moving to strengthen its own capabilities, planning talks with the United States on raising the warhead limits on its missiles and taking steps to place additional launchers to a US anti-missile defense system in the country's southeast.

South Korea has also been testing new missiles of its own, including the 800-kilometer (497 mile)-range Hyunmoo-2. Although the missile has not been operationally deployed yet, it is considered a key component to the so-called "kill chain" pre-emptive strike capability the South is pursuing to cope with the North's growing nuclear and missile threat.
