YEREVAN/BAKU (Reuters) - The Armenian parliament on Wednesday failed to discuss the prime minister’s resignation demanded by thousands of protesters over a ceasefire that secured territorial advances for Azerbaijan in Nagorno-KarabakhThe ceasefire, announced on Tuesday, ended six weeks of fighting - the worst in the mountain enclave for decades - and has been celebrated as a victory in Azerbaijan. Thousands of Armenians protested in the capital Yerevan, demanding Prime Minister Nikol Pashinyan step down, and several hundred marched on parliament. Some chanted “Nikol is a traitor”. Others shouted: “Nikol, leave.” Pashinyan has said he had no choice but to sign the agreement to prevent further territorial losses. He said he was taking personal responsibility for the setbacks, but rejected calls to step down. Parliament announced it would hold a special session on Wednesday evening to discuss the calls for his resignation, but it was not held as the parliament, dominated by Pashinyan’s supporters, failed to have a quorum. Opposition leaders called on protesters outside the parliament to leave and promised to share their future plans on Thursday.
