Thai and Cambodian leaders are meeting in Malaysia in an urgent effort to resolve deadly border clashes that entered a fifth day despite mounting international calls for peace.

PUTRAJAYA, Malaysia (Reuters) -The leaders of Thailand and Cambodia have agreed to an immediate and unconditional ceasefire to end their border clashes, Malaysian Prime Minister Anwar Ibrahim said on Monday, following talks in Malaysia between the two Southeast Asian neighbours.
