BBC- A Cambodian man (a Thai national) has been arrested for allegedly spying for Thailand as a major cross-border row intensifies.

Siwarak Chothipong, 31, who works for the Cambodia Air Traffic Service, was accused of seeking out the flight details of Thaksin Shinawatra.
The former Thai prime minister, wanted in Thailand to serve a jail sentence for corruption, has been playing golf with Cambodian Prime Minister Hun Sen.
Mr Thaksin's presence in Cambodia has outraged Thailand.
Bangkok fears Mr Thaksin's ability to spur opposition to the current government and resents Cambodia's rejection of an extradition request.
In exile for two years, Mr Thaksin accepted a role as economic adviser to the Cambodian government and arrived in the capital, Phnom Penh, on Tuesday.
Espionage charge
Siwarak Chothipong was arrested and charged with supplying Thailand with details of Mr Thaksin's flight schedule, said Cambodian national police spokesman Kirt Chantharith.
