Tensions flared Tuesday on Cambodia's border with Thailand, as a Thai soldier was injured by a landmine and about 100 Thai troops were held near an ancient temple in a territorial dispute.

Officials in both countries called the incident a misunderstanding that occurred after the soldiers went to fetch three Thai protesters arrested earlier in the day for jumping an immigration checkpoint to reach the Preah Vihear temple.

But later a Cambodian government spokesman said the Thai troops were being held until further talks could resolve the stand-off.
