In recent months, long-running border tensions between Thailand and Cambodia have been reignited following an incident in May during which one Cambodian soldier was killed.

The death occurred when Cambodian soldiers were digging trenches near an area Thailand disputed was theirs, before gunfire was exchanged.

Tensions have been heightened ever since, with both sides massing troops at different checkpoints along the 800-kilometer (480-mile) border.

In recent days, Thailand has closed a border at Chong Sai Taku in Buriram, while Cambodia has closed two checkpoints in its Oddar Meanchey province.

Thailand and Cambodia have 17 official crossings, but the busiest border connects Sa Kaeo province in Thailand with Cambodia's Poipet.

Both Thai and Cambodian nationals cross here for work, while the border is also a popular place for Thais to visit Cambodia's casinos. International tourists also use the crossing.

But following the clash at Chong Bok, far to the east near Laos, Thailand decided to reduce operating hours at Sa Kaeo by eight hours.

The crossing now opens between 8 a.m. and 4 p.m., having previously been open from 6 a.m. to 10 p.m. That change has affected day-to-day life for those living and working nearby.
