to expel Armenians from the enclave. In 1992, a war broke out and pogroms of Armenians and Azeris forced both groups to flee their homes. In 1994, a Russian-brokered ceasefire ended the war but more than 1 million ethnic Armenians and Azeris are still not able to return home. The conflict over Nagorno-Karabakh remains unresolved despite negotiations, that are ongoing since 1992 under the aegis of the Minsk Group of the OSCE, to resolve the conflict peacefully.
