Residents on both sides of Thailand's and Cambodia's border evacuated in droves on Monday as fresh clashes erupted, killing at least five people.

Both sides have each accused the other of starting the violence, which is the most serious confrontation between the two countries since they agreed to a ceasefire in July.

Thailand's Prime Minister Anutin Charnvirakul states that his country 'never wanted violence' but will 'use necessary means to preserve its sovereignty', while Cambodia's former leader Hun Sen accused Thai 'invaders' of provoking retaliation.

Since May, escalating tensions between the neighbours have led to over 40 deaths, import bans, and travel restrictions.

On Monday, the Thai army reported that its troops had responded to Cambodian fire in Thailand's Ubon Ratchathani Province, including launching air strikes along the contested border, while Phnom Penh's defense ministry claimed the Thai forces attacked first.

At least one Thai soldier and four Cambodian civilians have died, with numerous others injured due to the fighting.

Many local teachers express concern for children caught in the conflict, as it severely disrupts their education. Nearly 650 schools across multiple Thai provinces have been closed for safety.

The century-old border dispute dramatically escalated with significant military exchanges in July, following which an immediate ceasefire was agreed upon but has little enduring effect as tensions quickly resumed.

As military tensions rise, local communities grapple with the fear and uncertainty regarding their safety and future livelihoods.
