At least 12 people have died as violent clashes escalate along the Thailand-Cambodia border. Amid the rising tensions, Thailand has closed its border with Cambodia.

One of Thailand’s six F-16 fighter jets along its disputed border fired into Cambodia and destroyed a military target, according to Reuters, which cited the Thai army. The outlet added that Cambodia’s Ministry of National Defense said the jets dropped two bombs on a road. The ministry said that it “strongly condemns the reckless and brutal military aggression of the Kingdom of Thailand against the sovereignty and territorial integrity of Cambodia,” according to Reuters.

The U.S. Embassy in Bangkok and the U.S. Embassy in Phnom Penh advised American citizens living in or traveling near the border area to follow the directions of local security personnel. 

This comes almost exactly one month after both embassies warned U.S. citizens in their respective countries against going near the border. The State Department issued a “Level 1 with risk” travel advisory — just above the lowest level — urging Americans to exercise caution, though travel is permitted.

While it is unclear how the latest clashes between Cambodia and Thailand began, the violence follows a dispute in May, during which troops from both sides exchanged fire. According to The Associated Press, both sides said they acted in self-defense and one Cambodian soldier was killed. 

Following the flare-up in May, both countries took retaliatory actions, with Thailand stopping nearly all border crossings before ultimately closing them entirely. Meanwhile, Cambodia banned Thai movies and TV.
