BANTEAY MEANCHEY, Cambodia - Ms Sao Sopha was heavily pregnant when she left home with her son and cab driver husband in search of safety on Dec 9, a day after military clashes flared up again between Cambodia and Thailand.

“I am worried and scared because bullets were flying over my roof and the roof was shaking,” said Ms Sopha, 27, who is from O’Beichoan commune in north-western Banteay Meanchey province, near the border with Thailand.
