SISAKET, Thailand (Reuters) -Fighting on the Thai-Cambodian border extended into a third day and new flashpoints emerged on Saturday as both sides sought diplomatic support, saying they had acted in self-defence and calling on the other to cease fighting and start negotiations.

Cambodia has called for an "immediate" ceasefire with Thailand, after two days of cross-border fighting between the two South East Asian neighbours. Cambodia's ambassador to the UN, Chhea Keo, said his country asked for a truce "unconditionally", adding that Phnom Penh also wanted a "peaceful solution of the dispute".
