BANGKOK, Thailand -- Thailand and Cambodia reaffirmed their shaky ceasefire violation after days of fighting along their border, as China stepped into negotiate with the two countries.

Casualties include an 8-year-old Thai boy and multiple Cambodian civilians. Thousands of displaced families are sheltering with monks, NGOs and volunteers as schools and markets close across the border region.

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.
