Turkish President Recep Tayyip Erdogan welcomes Armenian Prime Minister Nikol Pashinyan in Istanbul to begin talks, which Yerevan has described as a „historic“ step toward regional peace. Armenia and Turkey have never established formal diplomatic ties and their shared border has been closed since the 1990s. Relations between the two nations have been historically strained over the World War I-era mass killings of Armenians in the Ottoman Empire — atrocities Yerevan says amount to genocide. Turkey rejects the label. IMAGES
