Thailand and Cambodia accuse each other of shelling after a ceasefire call by U.S. President Trump. Both countries disagree on who initiated the conflict, which has already led to over 30 deaths and significant evacuations.

The two nations have been locked in a decades-long conflict over their contested border. Tensions in disputed territories soured earlier this year.

Cambodia and Thailand each said the other had launched artillery attacks across contested border areas early on Sunday, hours after U.S. President Donald Trump said the leaders of both countries had agreed to work on a ceasefire.
