YEREVAN, ARMENIA -- Political tensions in Armenia heightened Monday, with supporters of the embattled prime minister and the opposition each holding massive rallies at separate sites in the capital.
Prime Minister Nikol Pashinyan has faced opposition demands to resign since he signed a peace deal in November that ended six weeks of intense fighting with Azerbaijan over the Nagorno-Karabakh region. The Russia-brokered agreement saw Azerbaijan reclaim control over large parts of Nagorno-Karabakh and surrounding areas that had been held by Armenian forces for more than a quarter-century.
Opposition protests seeking Pashinyan's ouster abated during the winter but intensified last week amid a rift between him and the country's military leaders.
The spat was sparked by Pashinyan firing a deputy chief of the military's General Staff who had laughed off the prime minister's claim that only 10% of Russia-supplied Iskander missiles that Armenia used in the conflict exploded on impact.
The General Staff then demanded Pashinyan's resignation, and he responded by dismissing the General Staff chief, Col. Gen. Onik Gasparyan. The dismissal has yet to be approved by Armenia's largely ceremonial president, Armen Sarkissian, who sent it back to Pashinyan, saying the move was unconstitutional.
Pashinyan quickly resubmitted the demand for the general's ouster, and the prime minister's allies warned that the president could be impeached if he fails to endorse the move.
Sarkissian's office responded with a strongly worded statement condemning "inadmissible speculation" about his move and emphasizing that his decision was "unbiased and driven exclusively by national interests."
Addressing a rally of thousands of his supporters, Pashinyan voiced hope the president would endorse the dismissal of the General Staff's chief for meddling in politics.
He blamed the country's former leader who lost power in the 2018 "velvet revolution" for influencing the military brass and trying to "set the army against the legitimately elected authorities and the people."
The prime minister also suggested calling a constitutional referendum in October to ask voters about expanding presidential powers to avoid future crises, although he didn't spell out specific changes.
After an hour-long speech, Pashinyan led his supporters on a march across Yerevan under the heavy escort of police and security officers.
Thousands of opposition supporters rallied at a separate location, demanding that the prime minister resign, and some later marched to the president's residence to support him in the rift with Pashinyan.
The two marches proceeded along separate routes amid tight police cordons. At one point, scuffles broke out between some from the rival camps, but police quickly pulled them apart.
Amid the escalating tensions earlier in the day, a group of protesters broke into a government building in central Yerevan to press for Pashinyan's resignation, but they left shortly afterward without violence.
Ishkhan Saghatelyan, a leading member of the opposition Dashnaktsutyun party, promised that the protests will continue Tuesday. He also called for another rally Wednesday, when Pashinyan is expected to appear in parliament. Saghatelyan urged opposition supporters to gather in front of parliament that day "to clearly convey our voice."
Pashinyan, a 45-year-old former journalist who came to power after leading large street protests in 2018 that ousted his predecessor, still enjoys broad support despite the country's humiliating defeat in Nagorno-Karabakh and the opposition calls for his resignation.
The prime minister has defended the peace deal as a painful but necessary move to prevent Azerbaijan from overrunning the entire Nagorno-Karabakh region, which lies within Azerbaijan but was under the control of ethnic Armenian forces backed by Armenia since a separatist war there ended in 1994. The fighting with Azerbaijan that erupted in late September and lasted 44 days has left more than 6,000 people dead. Russia has deployed about 2,000 peacekeepers to monitor the Nov. 10 peace deal.
Armenia has relied on Moscow's financial and military support and hosts a Russian military base -- ties that will keep the two nations closely allied regardless of the outcome of the political infighting.
Last week, the Russian Defence Ministry rebuked the Armenian leader for criticism of the Iskander missile, a state-of-the-art weapon touted by the military for its accuracy. The Russian military said it was "bewildered" to hear Pashinyan's claim because Armenia hadn't used an Iskander missile in the conflict.
In a bid to repair the damage to Armenia's ties with Moscow, Pashinyan rescinded his claim Monday, acknowledging that he made the statement after being misled.
