Cambodian soldiers escorted military delegates from five countries to see Thai shelling evidence along the border.

Troops led the contingent to a barbed wire fence installed by the Thai military in Pursat, opposite Thailand's Trat province, on September 3.

The group, headed by Colonel Nazlee bin Abdul Rahim, Defence Attaché of Malaysia to Cambodia, observed the allegedly shell-stricken area as Thai soldiers looked on.

The visit came after Thai forces toured 14 military officials along the border just a day earlier.

Led by Commander Theeraphon Lamyaisathit of the Royal Thai Marine Task Force, they inspected the border and were briefed on sniffer dog operations and unexploded ordnance left behind from the 1960s and 70s, when the US annihilated villages across the region.

The group, including representatives from Brunei, Malaysia, Laos, Indonesia, Myanmar, the Philippines, Singapore and Vietnam, also attended a presentation by Royal Thai Navy spokesman Captain Pavichaya Waleesuksan on the ongoing conflict.

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 that dozens of people have been killed and more than 300,000 displaced on both sides of the border.

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

American activist Michael Alfaro, who claimed to have visited the region on behalf of the White House, said the conflict showed few signs of abating and urged the countries to follow the ceasefire brokered by President Trump.
