Dozens of people – the count had reached 37 by the time of reporting – were killed in a suicide double bomb attack on Moscow’s metro station earlier this morning.  The first blast happened at Lubyanka station, the second at Park Kultury.  North Caucasus terrorist groups are thought to be responsible, but no one has claimed the blast as yet.  Moscow Mayor Yury Luzhkov, conveying information apparently received from the FSB, said that the attack was carried out by ‘two female terrorist suicide bombers‘.  The Guardian and the BBC are liveblogging new developments and information, and Reuters has a timeline of similar attacks over the last 15 years.  The BBC looks at the history of Moscow’s metro system.  There were a number of protests all over the country this weekend: Sunday saw a 1,500–4,000-strong (depending on your source), anti-government and uniformly anti-United Russia protest in Arkhangelsk. ‘I do not believe United Russia because they have plundered us and gave all we had to corrupt bureaucrats,‘ said one protester.  Smaller protests took place on Saturday in various locations to protest the reopening of the Lake Baikal paper mill, and the rise in utility prices.
