Fighting is again raging along the long-disputed border region between Thailand and Cambodia,raising concerns for British tourists.

As many as 12 people,including an eight-year-old boy,have been killed in the armed clashes – centred in the Thai Surin province and the Cambodian Oddar Meanchey province – with both sides blaming each other for firing the first shot.

An F-16 jet has been deployed by Thailand,firing into Cambodia multiple times and destroying a military target. Meanwhile,artillery and rockets have been fired from the Cambodian side.

This conflict has been simmering for months – with diplomatic relations deteriorating – and in fact the dispute over the region goes back almost a century.

Why are Thailand and Cambodia fighting?

At the heart of the conflict are differing interpretations of the colonial-era maps drawn more than a century ago by the French – who once colonised Cambodia – and by Siam (modern-day Thailand). Smoke rises from a convenience store at a gas station,amid the clashes between Thailand and Cambodia (Picture: Reuters)Cambodia has been using the 1907 map as a reference to claim territory,but Thailand has argued it was never officially accepted.This ambiguity led to a ruling by the International Court of Justice (ICJ) in 1962,which awarded the land and the 11th-century temple Preah Vihear to Cambodia.
