Washington has urged the leaders of Myanmar's new military regime to refrain from violence and relinquish power, after the death of a young anti-coup protester sparked new anger against the junta.

Much of the country has been in uproar since troops deposed civilian leader Aung San Suu Kyi on February 1, with large street demonstrations in both urban centres and isolated villages.

Global pressure against Myanmar's generals was swelling Friday after Britain and Canada imposed targeted sanctions, though the military showed no sign of deviating from its bid to crush opposition to their coup.

Hackers targeted Myanmar government websites Thursday to protest against the military coup, as the junta pressed on with its attempts to stymie nationwide opposition with internet blockades and troop deployments.

Myanmar's anti-coup protesters returned to the streets in force on Wednesday with the biggest street demonstrations since troops fanned out around the country to quell opposition to the new military junta. 

Thousands of people rallied in Yangon, the nation's biggest city, with protesters blockading roads with vehicles to stop security forces from moving around the commercial capital.

Myanmar's generals imposed a second straight overnight internet shutdown into Tuesday, ignoring international condemnation as they worked to grind down a popular uprising against their coup.

Myanmar's deposed leader Aung San Suu Kyi will appear in court via video conference this week over charges brought against her by the new military junta, her lawyer said Monday.

Myanmar's junta cut the nation's internet and deployed extra troops around the country on Monday as it intensified a crackdown on anti-coup protests, but defiant demonstrators again took to the streets. 

Opposition to Myanmar's new military regime intensified on Saturday as spontaneous neighbourhood watch groups mobilised to thwart arrests of anti-coup activists and the UN demanded the release of ousted leader Aung San Suu Kyi.

Myanmar's military regime braced for a seventh straight day of street protests on Friday after Washington announced sanctions on leaders of the coup that ousted civilian leader Aung San Suu Kyi.

Anti-coup protesters on Thursday took to the streets of Myanmar for a sixth consecutive day, after US President Joe Biden announced sanctions against the Southeast Asian nation's generals and demanded they relinquish power.

There has been an outpouring of anger and defiance since the military ousted civilian leader Aung San Suu Kyi last week and detained her along with other senior figures of her National League for Democracy party.
