On 6 July, Azerbaijan’s president said peace talks with Armenia to settle the long-standing Nagorno-Karabakh conflict had stalled. He called talks between the countries' foreign ministers ‘pointless’. The Organisation for Security and Co-operation in Europe (OSCE) has long been trying to mediate a settlement of the conflict, which dates back to the 1990s. On 12 July clashes involving tanks and artillery erupted again on the border between the two ex-Soviet republics. On 14 July Azerbaijan's military reported four deaths, but said it had destroyed an Armenian fortification and artillery, while Armenia had not reported any deaths on its side in the clashes. Azerbaijan’s president said, ‘Armenia's political and military leadership will bear the entire responsibility for the provocation’, while Armenia accused its neighbour of ‘using artillery in an attack aimed at capturing Armenian positions’.
