LONDON -- At least seven civilians have been killed and approximately 20 others have been injured in Cambodia amid renewed border clashes with neighboring Thailand, according to the Cambodian Ministry of National Defense.

Meanwhile, Thailand has 493 military aircraft compared with Cambodia’s 25, with Bangkok operating modern fighter jets like the Saab Gripen and F-16s, plus transport aircraft and helicopters. Where Phnom Penh does have more numbers are rocket projectors, with 463 to 26, suggesting its priority is artillery and ground-based firepower.

The renewed fighting along the Thailand-Cambodia border puts a spotlight on two militaries with a large gap in capabilities and numbers and a history of armed clashes along their 500-mile (800-kilometer) border.
