Disturbing body camera video shows a Utah nurse being arrested for refusing to draw blood from a patient for police who had no warrant. Alex Wubbels was the charge nurse on staff at the University Hospital of Utah when she was arrested by Salt Lake City police detective Jeff Payne on July 26, 2017.(Published Friday, Sept. 1, 2017) Early Sunday, the U.S. Geological Survey reported that a seismic event was recorded in North Korea. The event was a "possible explosion, located near the site where North Korea has detonated nuclear explosions in the past," the USGS said on its website, adding to suspicion that North Korea did in fact conduct another nuclear test. In July North Korea conducted its first ever ICBM tests, part of a stunning jump in progress for the country's nuclear and missile program since Kim rose to power following his father's death in late 2011. The North followed its two tests of ICBMs, which, when perfected, could target large parts of the United States, by threatening to launch a salvo of its Hwasong-12 intermediate range missiles toward the U.S. Pacific island territory of Guam in August. It flew a Hwasong-12 over northern Japan last week, the first such overflight by a missile capable of carrying nukes, in a launch Kim described as a "meaningful prelude" to containing Guam, the home of major U.S. military facilities, and more ballistic missile tests targeting the Pacific. To back up its bombast, North Korea needs to conduct nuclear tests. The first of its two such tests last year involved what it claimed was a hydrogen bomb; the second it said was its most powerful detonation ever. Experts and outside governments are skeptical of the hydrogen claim, but it is almost impossible to independently confirm North Korean statements about its highly secret weapons program. It is clear, however, that each new missile and nuclear test gives the North invaluable information that allows big jumps in capability. A key question is how far North Korea has gotten in efforts to consistently shrink down nuclear warheads so they can fit on long-range missiles. Top News Photos of the Week "Though we cannot verify the claim, (North Korea) wants us to believe that it can launch a thermonuclear strike now, if it is attacked. Importantly, (North Korea) will also want to test this warhead, probably at a larger yield, to demonstrate this capability," said Adam Mount, a senior fellow at the Center for American Progress. North Korea's claim that "this warhead is variable-yield and capable of specialized weapons effects implies a complex nuclear strategy. It shows (North Korea) is not only threatening assured destruction of the U.S. and allied cities in the event it is attacked, but also that (North Korea) is considering limited coercive nuclear strikes, or is seeking credible response options for U.S. ones." North Korea is thought to have a growing arsenal of nuclear bombs and has spent decades trying to perfect a multistage, long-range missile to eventually carry smaller versions of those bombs. South Korea's main spy agency has previously asserted that it does not think Pyongyang currently has the ability to develop miniaturized nuclear weapons that can be mounted on long-range ballistic missiles. Some experts, however, think the North may have mastered this technology. The White House has referred questions about North Korea's claims to intelligence officials, according to NBC News. "We know North Korea has been working on more advanced nuclear weapons. In fact they claimed their January 2016 test was an H bomb. If it was, it clearly wasn't a success. We expect their next nuclear test - whenever it occurs - will again be of an advanced nuclear weapon design," a senior official in the Trump administration told NBC News.
