In a case of very disturbing bluster (but, we hope, still just bluster) Ukrainian parliamentarian Pavlo Rizanenko told the Western media that Ukraine may have to arm with nuclear weapons if the US and other world powers refuse to enforce a security pact that he said obliges them to act against Moscow's takeover of Crimea. "We gave up nuclear weapons because of this agreement," said Rizanenko of the Ukrainian Democratic Alliance for Reform (UDAR). "Now there's a strong sentiment in Ukraine that we made a big mistake." (KSDK, March 10) Rizanenko was refering to the 1994 Budapest Memorandum on Security Assurances. Late last month, Ukraine's parliament, the Verkhovna Rada, formally invoked the Memorandum. In their statement, lawmakers said: "Ukraine received guarantees of country's security in the 1994 Budapest memorandum on security assurances over Ukraine's accession to the Nuclear Non-Proliferation Treaty."

In response to the Crimea crisis, EU Energy Commissioner Guenther Oettinger announced he is to delay talks with Russia on the South Stream gas pipeline that would export Russian gas via the Black Sea. The South Stream line strategically bypasses Ukraine, which currently hosts the main arteries for export of Russian gas. (Reuters, March 10) The European Commission has already postponed discussion of the OPAL pipeline, part of the Nord Stream project, which similarly bypasses Ukraine via the Baltic Sea. (Voice of Russia, March 11) Russia's giant Gazprom, which uses the existing Nord Stream line to send gas to Germany, plans to start shipments to Europe through the South Stream line at the end of 2015. Russia is seeking to boost gas exports to Europe as much as 23% over the next 20 years.

A group of some 50 gunmen seized control of parliament and government buildings in Simferopol, capital of the Ukrainian region of Crimea, raising Russian flags above them Feb. 27—just as the US warned Russia that military exercises planned near the border of Ukraine could "lead to miscalculation." With the top floor of the building occupied by the gunmen, Crimea's parliament voted to hold a referendum on the region's future—whether to remain in Ukraine or join Russia. Earlier, in his first statement since being voted out of office by MPs last week, Ukraine's fugitive ex-president Viktor Yanukovich said he had been "compelled to ask the Russian Federation to ensure my personal security from the actions of extremists," and that he still considered himself the legitimate president of Ukraine. The Ukrainian parliament in Kiev meanwhile voted to send Yanukovich to The Hague to be tried over the violence that led to at least 82 deaths in Kiev last week.

At least 25 are reported dead and more than 240 injured in clashes that erupted when Ukrainian protesters mounted a march on parliament Feb. 18, apparently ending a "truce" that had been worked out to allow negotiations. The march took place before a scheduled debate on reinstatement of Ukraine's 2004 constitution, which would rein in President Viktor Yanukovich's powers. The situation on the streets escalated as the bill was blocked by parliamentary staff who refused to register it on procedural grounds. The 2004 constitution was repealed in 2010, shortly after Yanukovich came to power, replaced by a new one granting him sweeping powers, including to appoint regional governors—a critical issue in Ukraine, with its divide between the more Russian-identified east and more European-identified west.

The main opposition party in Sri Lanka, the United National Party (UNP), released a statement Feb. 13 demanding the government conduct an investigation into alleged war crimes that occurred during the 26 year Sri Lankan civil war that ended in 2009. The Sri Lankan government and the rebel Liberation Tigers of Tamil Eelam (or Tamil Tigers) have both been accused of war crimes and human rights violations, primarily in the final months of the conflict. According to the AP, the government has been accused of deliberately shelling civilians, blocking food and medicine for civilians trapped in the war zone and deliberately undercounting civilians caught up in fighting. The Tamil rebels have been accused of using civilians as human shields, killing those who tried to escape their hold and recruiting child soldiers. According to a November 2012 UN report (PDF) an estimated 40,000 Tamil civilians were killed in the final months of the conflict.

A French court in Aix-En Province on Jan. 9 ordered the extradition of Mukhtar Ablyazov, Kazakhstan's former energy minister, accused of misappropriating $6 billion from BTA Bank. The French court agreed to the extradition requests from Russia and Ukraine, which both house BTA Bank branches, partly because France does not have an extradition agreement with Kazakhstan. In 2011 Ablyazov gained political asylum in the UK after alleging that he faced prosecution in Kazakhstan because he was the leading figure in the opposition against Kazakhstan president Nursultan Nazarbayev. Ablyazov also claimed that he had been imprisoned for political reasons prior to these charges. Amnesty International  urged against Ablyazov's extradition after the court's ruling. Julie Hall, AI expert on counter-terrorism and human rights, said, "Not only do we have fears that Ablyazov would not get a fair trial in Russia or Ukraine, there is a real danger that he will eventually end up in Kazakhstan, where he will be at risk of torture and other ill-treatment." She cited a report (PDF) on the routine cooperation of Russia and Ukraine with Central Asian republics, including Kazakhstan, to transfer suspects, often at risk of their human rights.

New violence is reported from China's far western province of Xinjiang Nov. 16, when a group of Uighur youths attacked the police station in Siriqbuya (Chinese: Selibuya) township, Maralbeshi (Bachu) county, Kashgar prefecture. Two auxiliary officers were bludgeoned to death, and all nine of the attackers were reported to be killed. The youths were said to be armed with knives, swords and sickles The same town was also the scene of deadly clashes in April. Radio Free Asia, citing eyewitness accounts (presumably via cellphone), reported that "residents pleaded with the police not to kill the young Uyghurs"—implying at least some of the deaths may have been extrajudicial executions carried out after the attackers were pinned down or subdued.

Ethnic Uighurs from around the world gathered in Washington DC this week to commemorate the anniversary of two short-lived independent republics set up by their forefathers within what is today the Xinjiang Uighur Autonomous Region of China. Around 100 Uighurs attended a ceremony Nov. 12 at Capitol Hill to remember the establishment of the East Turkestan republics on Nov. 12 in 1933 and 1944. Rebiya Kadeer, president of the Munich-based World Uyghur Congress, praised  those who founded the republics, and called on the Uighur people to remain strong in the face of what she called a policy of "repression" under the current Chinese government. "The Uyghur people have been suffering under the oppressive government of China since the destruction of the Uyghur republics; however, the level of repression has since been extended to our beliefs and customs," she said at the ceremony at the Rayburn House of Representatives Office Building.
