Cambodia has shut its border crossings with Thailand, as fighting continues between the two forces on Saturday despite US President Donald Trump earlier saying they had agreed to a ceasefire.

The crossings will be closed until further notice, according to Cambodia's interior ministry.

Earlier, Thai Prime Minister Anutin Charnvirakul said he told Trump a ceasefire would only be possible after Cambodia had withdrawn all its forces and removed landmines.

Thai officials said four soldiers were killed on Saturday, as both sides reported continued bombing and artillery exchanges. Cambodia has not been updating its military casualty figure.

Cambodia's defence ministry stated that Thai fighter jets bombed hotel buildings and a bridge, while Thailand reported injuries to several civilians from a Cambodian rocket attack.

The four deaths on Saturday bring Thailand's total military death toll since Monday to 15, along with 270 others injured and six civilian injuries. Cambodia reported at least 11 civilian deaths and 59 injuries earlier this week.

In the context of the ongoing military conflict, approximately 700,000 individuals have been evacuated from both nations.

Trump had previously asserted that he could prevent further fighting merely by contacting the leaders of both countries. After discussions with them, he announced an agreement for an immediate ceasefire, highlighting a peace commitment.

However, neither side indicated a ceasefire was imminent in their subsequent comments. Anutin insisted that Thailand was not the aggressor and emphasized the necessity for Cambodia to demonstrate troop withdrawal and landmine removal.

Cambodia's leadership maintains its position to fight for national sovereignty, with prior instances of tariff implications not mentioned as leverage this time around. The ongoing conflict has a long-standing history rooted in territorial disputes which continue to this day, escalating tensions in the region.

This week saw Thai air strikes targeting areas inside Cambodia while Cambodia retaliated with rocket barrages. The two countries, engaged in territorial disputes for over a century, continue to blame each other for initiating violence.
