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.

The ceasefire reached in Malaysia was supposed to take effect at midnight on Monday, but it was quickly tested as Thailand and Cambodia continued to accuse each other of violating the truce agreements.

A ceasefire between Thailand and Cambodia appeared to largely be holding on Tuesday as military commanders from both countries met for negotiations, even as the Thai army accused Cambodian troops of violating the truce overnight.
