YANGON: Opponents of Myanmar's coup planned more protests on Saturday as international pressure on the military junta to halt its repression of pro-democracy supporters increased, with Asian neighbours joining Western countries in condemning lethal force.

Two people were killed when soldiers opened fire overnight in the northern ruby mining town of Mogok, the Myanmar Now news portal reported. That took the death toll since the Feb. 1 coup to 237, according to a tally by the Assistance Association for Political Prisoners activist group.

The bloodshed has not quelled the anger over the ouster of the elected government and the detention of its leader, Aung San Suu Kyi, though some protest organisers say they have to adapt their tactics.

"We protest where there are no police or military, then when we hear they're coming, we disperse quickly," campaigner Kyaw Min Htike told Reuters from the southern town of Dawei.

"I don't want to lose a single one of my comrades but we'll protest any way we can until our revolution prevails."

In other towns, people have been gathering at night to hold up candles and protest banners and pose for photographs before melting away.

U.N. Secretary-General Antonio Guterres on Friday condemned what he denounced as the military's continuing brutal violence. A "firm, unified international response" was urgently needed, his spokesman quoted him as saying.

U.N. rapporteur Tom Andrews called for sanctions to what he called the generals' ruthless attacks on the people.

"The world must respond by cutting their access to money and weapons. Now," he wrote on Twitter.

The U.S. House of Representatives approved legislation condemning the coup and lawmakers decried the increasingly harsh tactics against the demonstrators.

Authorities have tightened restrictions on internet services, making information increasingly difficult to verify, and clamped down on private media.

Ambassadors of Western countries condemned the violence as "immoral and indefensible", in the Hlaing Tharyar industrial district of the commercial capital Yangon, where dozens were killed over several days after Chinese-owned garment factories were torched last weekend.

"Internet blackouts and suppression of the media will not hide the military's abhorrent actions," they said in a statement on Friday.

ASIAN ANGER

Asian neighbours, who have for years stuck to a code of not criticising each other's internal problems, have also been speaking out to urge an end to the violence.

Indonesian President Joko Widodo, in some of the strongest comments yet by a regional leader, said he would ask Brunei's Sultan Hassanal Bolkiah, the chairman of the Association of Southeast Asian Nations (ASEAN), to call an urgent meeting.

"Indonesia urges that the use of violence in Myanmar be stopped immediately so that there are no more victims," Jokowi said in a virtual address.

"The safety and welfare of the people must be the top priority."

Backing Indonesia's call for a meeting, Malaysian Prime Minister Muhyiddin Yassin said he was appalled by the persistent use of lethal violence against unarmed civilians.

Philippine foreign minister Teodoro Locsin said that ASEAN had to act.

Singapore has also spoken out against the violence and the coup that triggered it, calling for the release of Suu Kyi.

But the military has shown no sign of being swayed and has defended its takeover, which derailed a slow transition to democracy in a country that has been ruled by the army for most of its post-independence history.

It says a Nov. 8 election won by Suu Kyi's National League for Democracy was fraudulent and its claims were ignored by the electoral commission. It has promised a new election but not set a date.

Suu Kyi, 75, faces accusations of bribery and other crimes that could see her banned from politics and jailed if convicted.

Her lawyer says the charges are trumped up. The Nobel peace laureate, who has campaigned for democracy in Myanmar for three decades, is being held at an undisclosed location.
