Thailand on Friday warned that an escalating border conflict with Cambodia could soon escalate into war between the two countries, as scores of thousands flee the area.

On Thursday, Cambodian and Thai forces began exchanging fire near the ancient, disputed temple of Prasat Ta Muen Thom. Small arms fire quickly escalated into heavy artillery and missile fire, airstrikes, and the deployment of tanks and armored vehicles. Peace efforts have come to nought, as officials on both sides warn that the situation will likely continue to escalate.
