Thailand has released 18 Cambodian soldiers three days after both countries agreed to a renewed ceasefire. The soldiers had been detained since July during border clashes between the two Southeast Asian neighbors. Thailand’s foreign ministry confirmed the release, describing it as a gesture of goodwill and confidence-building. Cambodia’s defense ministry said the soldiers returned home on Wednesday morning after 155 days in Thai custody.

The border conflict, which began in July, had previously been halted through mediation by U.S. President Donald Trump and Malaysian Prime Minister Anwar Ibrahim. However, fighting resumed earlier this month, resulting in at least 101 deaths and the displacement of about half a million people from both sides. The two nations reached another ceasefire agreement over the weekend, which took effect on Saturday afternoon.

The soldiers were initially scheduled to be repatriated on Tuesday, but Thailand delayed the handover, citing alleged ceasefire violations. Cambodia denied those allegations, maintaining that it had not breached the agreement.
