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.

PUTRAJAYA, Malaysia (AP) — Thailand and Cambodia have agreed to an “immediate and unconditional” ceasefire in a significant breakthrough to resolve deadly border clashes that entered a fifth day, Malaysian Prime Minister Anwar Ibrahim said Monday.

Thailand said Tuesday that Cambodia violated their hours-old cease-fire that ended days of fighting between the neighbors over their disputed border.
