Thai nationalists staged a rally to support their military as border clashes continued with neighbouring Cambodia.

Footage shows patriots offering flowers to soldiers in front of the Royal Thai Navy Headquarters in Bangkok, Thailand, today.

The group, led by political activists Jatuporn Prompan, Nitithorn Lamluea, and Pichit Chaimongkol, held up Thai flags and displayed encouraging messages to the officers, hoping to boost morale during the conflict.

Phitchit said: ‘The purpose of this rally is to offer moral support to the Royal Thai Navy officers who sacrificed to perform their duties for protecting the nation's sovereignty amidst the border dispute with Cambodia.'

Protest speaker Samdin Lamai said: 'The people still support the military protecting the nation, but we cannot stand with a government that we no longer believe is acting in the country's interest.'

Commander Chonlaphu Chusri, deputy secretary of the Royal Thai Navy, thanked the group for the display of support. He assured them that the Navy will perform their duties to the best of their ability to protect national interests both on land and at sea, and asked the public to have confidence in them.

A bloody military confrontation flared in long-disputed border areas as Thailand and Cambodia accused each other of instigating the violence on July 24.

The Thai army claimed the clash began when six armed Cambodian soldiers approached a Thai outpost after a drone was heard near a disputed Khmer temple. Thai troops said they shouted warnings and claimed the Cambodians opened fire first.

However, Cambodia's Defence Ministry accused Thailand of provoking the violence, saying its forces acted in self-defence.

Officials said at least 43 people have been killed and more than 300,000 displaced on both sides of the border.

Both sides have reached a truce at midnight on Monday, following talks facilitated by Malaysian Prime Minister Anwar Ibrahim, chair of the Association of Southeast Asian Nations (ASEAN).

He said: 'This is a vital first step toward de-escalation and the restoration of peace and security.'

US President Donald Trump had earlier threatened to pause trade deals with both countries if clashes continued.

He said after the ceasefire was forged: 'By ending this War, we have saved thousands of lives ... I have now ended many Wars in just six months — I am proud to be the President of PEACE!'

However, Thai authorities accused Cambodia of allegedly violating the armistice, claiming Khmer soldiers were firing into Thai territory until Wednesday morning.

Thai government spokesman Jirayu Huangsab said the Thai army have 'maintained control of the situation' and the general conditions along the border were 'normal'.
