CNN reports April 26 of a "perilous face-off" as Russian state news complained that Ukraine has mobilized 15,000 troops in the suburbs of Slavyansk in the country's east "in order to wipe out the city and its residents." A Defense Ministry source said the number of Ukrainian troops put the pro-Russian militants who control the city at a disadvantage, as the latter are "armed only with small amount of pistols and shotguns." Of course, Russia's military massively outweighs Ukraine's and the Defense Ministry's statement is a barely veiled threat of intervention. Meanwhile, USA Today reports that Russian warplanes have entered Ukrainian airspace several times in the last 24 hours, according to the Pentagon. The violation of Ukraine's airspace follows war games that have moblized some 40,000 Russian troops to the Ukrainian border. Earlier this week, the Pentagon deployed 600 paratroopers to Poland and the Baltic states "to reassure NATO allies in the region about the US commitment to their defense." Ukrainian Prime Minister Arseniy Yatsenyuk charged that Moscow "wants to start World War III" by seeking to take over Ukraine.

There is something fundamentally wrong about the fact that there are apparently a whopping 400 tourists on Mount Everest at any one time. That's what came to light April 23, when 16 sherpa guides were killed in an avalanche. The sherpas went on strike over low pay for dangerous work, their walk-out leaving 400 jet-setters stranded on the mountain and jeopardizing the 2014 climbing season. About half the sherpas have descended from the base camp where they operate, and Ang Tshering Sherpa, president of the Nepal Mountaineering Association, said more will likely follow.

The Periodic Review Secretariat, a national security panel under the authority of the US Department of Defense (DoD), on April 24  recommended (PDF) the release of a Yemeni prisoner currently held at Guantánamo Bay. The prisoner, Ali Ahmad Mohamed al-Razihi, was suspected of acting as a bodyguard for Osama bin Laden and has been held at Guantánamo since 2002. The Periodic Review Secretariat determines whether certain individuals detained at Guantánamo represent a continuing significant threat to the security of the US such that their continued detention is warranted. In making the determination, the security review panel considered the detainee's plans for the future and the level of his involvement with al-Qaeda, including his behavior throughout detention. The journalist and Guantánamo expert Andy Worthington released a copy of al-Razihi's statement  delivered before the review board of the Periodic Review Secretariat on March 20.

Daily Kos is currently pushing a petition warning of the imminent demise of "net neutrality." It reads: "FCC Chairman Tom Wheeler has proposed a new set of rules that will allow Internet service providers to charge web publishers extra for preferential treatment. Large websites like Fox News could pay for priority service to ride in the fast lane and reach more people online—while independent blogs like Daily Kos, nonprofits, small businesses and any website that can’t afford it will be left out in the cold. The FCC will consider this 'pay-to-play' rule on May 15th, so let's nip it in the bud now." OK, we encourage readers to sign the petition, by all means. But we have little faith that online petitions really make much difference, or that this eventuality (inevitability?) can be nipped in the bud...

Lawmakers in Kosovo on April 22 voted 89-22 to create an EU-backed court that will investigate crimes committed by ethnic Albanian rebels during the 1998 war with Serbia. The move follows international pressure for Kosovo to open a state investigation into civilian killings committed by the rebel side. The court will be based in Kosovo, though most of the work will be carried out in the Netherlands. Similar to the operations of the International Criminal Tribunal for the former Yugoslavia (ICTY), the court will be run by international judges and lawyers. Rebels during the conflict allegedly killed approximately 400 civilians.

Central America's rainforests are being destroyed by drug traffickers who cut roads and airstirps on officially protected lands, according to a paper in the journal Science. The phenomenon, called "narco-deforestation," is occurring across large swaths of Guatemala and Honduras, and perhaps elsewhere. Erik Nielsen, an assistant professor in the School of Earth Sciences and Environmental Sustainability at Northern Arizona University, said: "Not only are societies being ripped apart, but forests are being ripped apart." He added that cattle ranches are being established on cleared land as fronts to launder drug money.

Pentagon chief Chuck Hagel toured Asia earlier this month ahead of Obama's coming visit, and at an April 10 stop in Ulan Bator signed a "joint vision" statement with his Mongolian counterpart Dashdemberel Bat-Erdene, calling for expanding military cooperation through joint training and assistance. "A strong US-Mongolia defense relationship is important as part of the American rebalance to the Asia-Pacific region," Hagel told a joint press conference. Bat-Erdene ruled out the possibility of hosting US forces, citing a Mongolian law that bars foreign military bases from the country. But the agreement is clearly aimed at extending US military encirclement of China. Days earlier, Hagel had lectured his hosts in Beijing over China's establishment of an air defense zone in the East China Sea. He also made a flat warning about the disputed Senkaku/Diaoyu islands, telling reporters: "We affirmed that since [the Senkaku Islands] are under Japan's administrative control, they fall under Article 5 of our Mutual Security Treaty." (AFP, April 10; Time, April 8)

A Saudi Arabian court on April 21 sentenced three people to death for their roles in attacks on expatriate resident compounds in Riyadh in May 2003, bringing the total death sentences to eight. Another 77 people have been sentenced to prison terms ranging from two to 35 years by the court, which was created to handle terrorism cases. The 2003 attacks, in which blasts at three residential compounds in Riyadh left 35 people dead, were part of a three-year campaign by al-Qaeda aimed at destabilizing Saudi Arabia. The identities of the 85 defendants have not been disclosed, though the Sabq news website has reported that five men sentenced to death a day earlier had been found guilty of assembling the car bombs used to attack the compounds. They have 30 days to appeal their sentences, all of which were handed down for charges of taking part or abetting in the attacks.
