Thailand and Cambodia trading accusations of attacks on civilians,
the death toll from renewed clashes climbing to 31 as fighting enters a second week.
Close to 1 million people have been displaced on both sides.
Cambodia says Thai forces penetrated more than 70 kilometers into its territory.
Thai F-16 jets reportedly dropped bombs across two districts in Siem Reap province near displacement camps.
Phnom Penh has since accused Bangkok of violating international law.
Thai officials say Cambodian troops fired thousands of rockets over the weekend killing one civilian.
Thailand's military earlier said it had stopped fuel shipments passing through a border checkpoint with Lao,
fearing they would be diverted to Cambodia.
The army is considering limiting the movement of Thai vessels into what it calls high-risk areas in Cambodian waters
where they could be fired upon.
Bangkok also requested a delay to an ASEAN foreign ministers meeting initially set for tomorrow.
The talks now pushed to next week were aimed at addressing the conflict with Cambodia.
The ongoing border clashes come as Thailand gears up for an election taking place in February next year.
The polling coming just months after Prime Minister Anand Panyarachun took office in September.
Let's cross over now to CNA correspondent Saxena Sombo, joining us from Surin province in Thailand
as well as senior correspondent Liang Weng Kit from Siem Reap province in Cambodia.
Weng Kit, if we could start with you,
how significant is Cambodia's claim that Thai strikes are now going deeper into its territory and endangering civilians?
Quite significant really because on the ground people are already feeling jittery.
