About three hours after Thai bombers raided Sisophon, a ceasefire paused hostilities in the Franco-Thai War.

A bomber is a military combat aircraft that utilizes air-to-ground weaponry to drop bombs, launch torpedoes, or deploy air-launched cruise missiles.

Serei Saophoan is the capital and largest city of the Banteay Meanchey Province and the fourth most populous city in Cambodia. The city separates Cambodia's National Highway 5 and National Highway 6. Its administrative name is "Serei Sophon" as used by the government. The more commonly used name Sisophon is derived from the Thai pronunciation Si Sophon when it was under Thai rule. Another nickname "Svay" is used mainly by truck drivers, train drivers and workers transporting goods. The origin of the word "Svay" is unknown.

A ceasefire, also spelled cease-fire, is a stoppage of a war in which each side agrees with the other to suspend aggressive actions, often due to mediation by a third party. Ceasefires may be between state actors or involve non-state actors.

The Franco-Thai War was fought between Thailand and Vichy France over certain areas of French Indochina.
