UNITED NATIONS/WASHINGTON -- 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.

Gunfire continued to be heard along the Thailand-Cambodia border in the early hours of Sunday, the National Broadcasting Services of Thailand reported, citing Thai army sources.

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.
