BANGKOK -- Armed clashes have broken out between Thailand and Cambodia in long-disputed border areas, rapidly escalating months-long tensions.

Thailand and Cambodia exchanged fire along their disputed border for a second day on Friday, officials from both countries said, with more than a dozen people reported killed and more than 135,000 civilians evacuated.

A personal feud between two of Southeast Asia’s political titans is inflaming the worst violence on the Thailand-Cambodia border in more than a decade.
