BANGKOK/PHNOM PENH/UNITED NATIONS/WASHINGTON - The armed border clashes between Thailand and Cambodia entered the 4th day on Sunday.

According to a statement issued by the Thai Foreign Ministry, Richa Suksuwanon, deputy spokesperson of the Thai army, said that the first shots were fired into Thai territory in several areas, including a civilian house, by Cambodia early Sunday.

Meanwhile, Cambodian Defense Ministry's Undersecretary of State and Spokesperson, Lieutenant General Maly Socheata, said that from 2:00 am to 6:00 am local time on Sunday, the Thai army fired artillery at various locations in the Preah Vihear and Oddar Meanchey provinces.

"Our forces have fought back actively and vigorously to defend our territorial sovereignty," she said.

Cambodian villagers flee

Socheata said about 80,000 Cambodian villagers have fled their homes for safe refuge as the armed clashes continued. 

"The number of evacuees in three provinces, namely Preah Vihear, Oddar Meanchey and Pursat, has risen to 25,000 families with up to 80,000 people," she said, adding that a total of 536 schools have been closed, affecting 130,000 students.

Since the armed clashes between Cambodian and Thai soldiers over disputed border areas broke out on Thursday, more than 30 people have been killed from both sides, and more than 100,000 people have been evacuated to safe areas, according to figures provided by the two countries.

Both sides have accused each other of violating international law and opening fire first.

Trump, UN chief urge ceasefire

UN Secretary-General Antonio Guterres and US President Donald Trump on Saturday urged Cambodia and Thailand to agree to a ceasefire.

Guterres urges both sides to immediately agree to a ceasefire and to address any issues through dialogue, with a view to finding a lasting solution to the dispute, said Farhan Haq, the UN chief's deputy spokesperson, in a statement.

Guterres "is deeply concerned about the continuation of armed clashes at the border between Cambodia and Thailand since 24 July," he said.

"The Secretary-General condemns the tragic and unnecessary loss of lives, injuries to civilians and the damage to homes and infrastructure on both sides," Haq said. The UN chief "remains available to assist in any efforts towards a peaceful resolution of the dispute."

On his social media platform Truth Social Saturday, Trump said that he has spoken to the Prime Minister of Cambodia and the Acting Prime Minister of Thailand to request a ceasefire between the two countries.

Thailand and Cambodia both want to have an immediate ceasefire and peace, according to Trump.

Trump also said the United States is currently dealing with trade with both countries, but he doesn't want to make any deal with either country if they are fighting.

"After speaking to both Parties, Ceasefire, Peace, and Prosperity seems to be a natural. We will soon see," he noted.

Cambodian Prime Minister Hun Manet on Sunday reiterated Cambodia's willingness for an "immediate and unconditional ceasefire" between the armed forces of Cambodia and Thailand after the phone discussion with Trump.

Thailand on Sunday also responded to Trump's call for a ceasefire, saying that the country agrees in principle to have a ceasefire in place but would like to see sincere intention from the Cambodian side.

Clashes in the border areas between Cambodia and Thailand began on Thursday, with both sides accusing each other of violating international law. The UN Security Council held an emergency meeting behind closed doors on Friday afternoon to deal with the clashes at the request of Cambodian Prime Minister Hun Manet.
