A British actor and his wife flew to the Thai-Cambodian border to donate supplies to Thai troops.

Mark Shelley, 62, and his spouse Naphatwarun Sirirattanasap, from Thailand, visited the Border Patrol Police station in Trat province amid mounting territorial tensions along the frontier.

Footage shows the couple handing snacks, bottles of water, and nine sets of solar panels to the soldiers on October 3.

Raising a small Union Jack flag, the actor said: 'Real, not filmed. So we need some help. I want my friends, farang, to help. Don't want money, little donation for food please.'

He later held a Thai flag, enthusiastically yelling: 'Thailand, fight, fight!'

Police Colonel Siamrath Rattanachanajan, chief of Border Patrol Police Company 116, led his unit to thank the couple for travelling all the way from England to donate goods.

He said: 'We especially needed solar panels to power our electronic devices due to the lack of electricity and internet in remote border areas. The solar panels will greatly help us.'

He said officers stationed in Trat have been fully prepared since the initial clashes with Cambodia, urging the public to stay calm and follow news from official sources.

Mark Shelley is a British actor who has worked in dozens of TV series, including Peaky Blinders and Downton Abbey.

Thailand and Cambodia have been fighting for more than a century over several undemarcated sections of their 817-kilometre (508-mile) border, which was originally mapped by France in 1907 while Cambodia was still its protectorate.

But tensions flared in the long-disputed frontier as both accused each other of instigating violence on July 24, which killed at least 48 and temporarily displaced some 300,000 on both sides of the border.

Cambodia claimed responsibility for the alleged war crime of firing rockets into Thailand that struck a gas station, killing a number of children.

The two nations have reached a shaky truce following talks facilitated by Malaysian Prime Minister Anwar Ibrahim, chair of the Association of Southeast Asian Nations (ASEAN).
