Azerbaijan forces tightens their grip on the breakaway region of Nagorno-Karabakh as international concern mounted over the plight of ethnic Armenian civilians trapped there. They displayed infantry weapons including sniper rifles, hundreds of Kalashnikov rifles, rocket-propelled grenades and four tanks painted with cross insignia, that they said they had seized from the separatists. Azerbaijani military spokesman Anar Eyvazov says they are working closely with Russian peacekeepers conducting the demilitarisation process. IMAGES AND SOUNDBITES
