Some 270 Armenian children have been cut off from their parents in the breakaway Azerbaijani region of Nagorno-Karabakh after Azerbaijan blocked the only road linking Armenia to the landlocked enclave. The children are now attending a school in Yerevan, where they came for a singing competition when the blockade began in December.

It’s not only an Azerbaijani blockade.
It’s a Russian blockade too.
Russia could end the blockade with a telephone call to Aliyev.
