At least 32 people have been killed in escalating border clashes between Cambodia and Thailand, with thousands forced to flee. Cambodia confirmed 12 new deaths—seven civilians and five soldiers—while Thailand reported 19 total fatalities, including children and soldiers.

Fighting erupted Thursday after a landmine injured five Thai troops near the disputed border. Both sides blame each other for initiating attacks, which include airstrikes and artillery fire. Cambodia has accused Thailand of using banned cluster munitions, while Thailand says Cambodia targeted civilian areas, according to Al Jazeera.

Over 150,000 people have been evacuated across both countries. Thailand has declared martial law in eight districts. The UN Security Council has urged both sides to show restraint and resolve the crisis peacefully.
