The U.S. Embassy is monitoring reports of significant escalation in the conflict along the Cambodia-Thailand border. On December 8, there were widespread reports of artillery and small arms fire exchanges in border areas. Thai military aircraft reportedly conducted strikes in Cambodia. Both sides continue to report cross-border fire, and the situation remains volatile.
