Fighting on the Thai-Cambodian border extended into a third day and new flashpoints emerged on Saturday as both sides said they had acted in self-defence in the border dispute and called on the other to cease fighting and start negotiations.

The first clash on Thursday morning took place near the ancient Ta Muen Thom temple along the border of Thailand's Surin province and Cambodia's Oddar Meanchey province, the AP reported.
