Ivan Vasilevich, 60, and his wife Lyudmila saw firewood in the village of Garenichi, some 110 km (68 miles) east of Minsk, December 14, 2011. Vasilevich used to work at a farm, often wearing rubber boots, and had his legs freeze over time. He then had to have them amputated 13 years ago after gangrene set in, and now earns money by weaving baskets. He weaves up to 25 baskets a month and sells them at a local market at a price of $2.50. Ivan has a disability pension of $140 a month, so the income he garners from weaving baskets is a significant amount for his family to subsist. REUTERS/Vladimir Nikolsky (BELARUS - Tags: SOCIETY)

Activists hold placards during a rally called "Patriotism is not fascism!" in Moscow, December 18, 2010. Activists held a rally to demand the mass media to cover recent events, involving right wing protesters and people from Russia's north Caucasus region, in an impartial and objective way, local media reported. Russian Prime Minister Vladimir Putin said on Thursday tough police action was imperative to stem extremism and warned that "liberal" criticism of the government threatened stability.

A human rights activist stands in St.Petersburg's central square with a poster reading: "No to Covering Up Crimes in Army!" during a protest February 2, 2006. The protest was staged after Russian army conscript Andrei Sychev, 19, was set upon in the New Year holiday in an Ural mountain tank academy by drunken soldiers, who reports say, held him semi-crouched for several hours and beat him. Sychev was given delayed - some say botched - medical help that allowed gangrene to develop and led to amputations of his legs, genitals and fingers.

A demonstrator holds a placard during a protest in front of the Russian defence ministry in Moscow January 28, 2006.

The placard's top picture shows Ivanov, quoting him as saying 'I was high up in the mountains. Nothing serious had happened'. The bottom picture shows conscript Andrei Sychev, 19, who was beaten for several hours by his superiors and given delayed - some say botched - medical help that allowed gangrene to develop and lead to amputations.
