China's much-vaunted abolition of its widely loathed "re-education through labor" camps risks being no more than a cosmetic change because of other rights abuses, Amnesty International said Tuesday.

Ukraine's embattled President Viktor Yanukovych sought Tuesday a multi-billion-dollar lifeline from Russia's Vladimir Putin that could relieve a brewing economic crisis but also stoke huge pro-EU protests roiling Kiev streets.

Massed ranks of military and party leaders pledged complete loyalty to North Korean leader Kim Jong-Un Tuesday on the second anniversary of his father's death, at a time of growing concern over the regime's stability.

The bodies of at least 21 people have been found after a grisly attack in eastern DR Congo in which several women and children were raped, mutilated and beheaded, the U.N. peacekeeping mission said Monday.
