Armenia on May 24 called on the UN's top judicial body, the International Court of Justice, to order its archrival Azerbaijan to withdraw a blockade from a key road connecting Yerevan to the breakaway region of Nagorno-Karabakh. On April 23, Azerbaijan set up a roadblock at the entrance to the Lachin Corridor, the only road linking Armenia to the region. Yerevan had previously accused Baku of blocking the vital artery for nearly six months. The region is populated mainly by Armenians who broke away from Baku with Yerevan's help.
