Hong Kong Protests Turn Violent.
Protesters in Hong Kong clashed with police yesterday, marching on the 22nd anniversary of Britain's handover of the region back to the Chinese government. Tens of thousands took to the streets (see photos), and for a tense three-hour period a faction of marchers broke into and occupied the legislative council building (see video of the dramatic entrance). Riot police eventually cleared the building with tear gas. The protests come on the heels of massive rallies over the past few weeks - with some estimates in the millions - demonstrating against an extradition bill that would allow anyone accused of a crime by the Chinese government to be sent to the mainland for trial. Hong Kong is the second-most densely populated area in the world and is the 35th-largest economy despite being three times smaller than Rhode Island (see stats), but has had fraught relations with the central government since the handover.

Record-breaking temperatures have settled in Alaska, with the capital city of Juneau breaking a 110-year mark at 83 degrees Fahrenheit. The heat triggered air advisory warnings and exacerbated a wildfire outside of Anchorage, which had consumed over 100 square miles. The heat follows an unusually warm spring that melted sea ice earlier than normal, with scientists recording sea surface temperatures 9 degrees above the 1981-2010 average. The high temperatures come as much of the rest of the US preps for a July 4th heatwave, with heat indices expected to range from 95 to 110 across much of the central and eastern parts of the country. Temperatures in the States may seem cool compared to Europe, with many countries currently experiencing temperatures over 110 degrees - temperature records have been smashed in parts of Germany, Poland, France, and Spain. 

Germany imposed a temporary speed limit on its Autobahn highways, out of concern that the high temperatures could cause the roads to buckle
Iran Breaks Nuclear Deal.
Iran passed production caps on low-enriched uranium imposed by the 2015 nuclear treaty yesterday, the latest sign that the multi-lateral deal may be on its last legs. The caps were a central component to the Obama-era pact that included the UK, France, Germany, China, and Russia (though the US left last year). Most commercial nuclear reactors rely on uranium with 3-5% of uranium-235 - an unstable form of the material that drives nuclear activity. Under the deal, Iran was limited to 660 pounds under the deal, though US officials are concerned that Iran will move towards higher-enriched material - weapons-grade uranium requires near 90% enrichment, but experts say that once 20% enrichment is achieved, higher enrichment levels can be reached fairly quickly. The news is the latest in spiraling tensions with Iran, following the downing of a US drone and attacks on oil tankers in the Strait of Hormuz.
