Thai reports claim Cambodia carried out overnight attacks ahead of officials from both countries meeting for a third day of negotiations on Friday

Cambodia has accused Thailand of intensifying its bombardment of disputed border areas, even as officials from the two countries attend a multi-day meeting aimed at negotiating an end to deadly clashes.

The neighbours’ longstanding border conflict reignited this month, shattering an earlier truce and killing more than 40 people, according to official counts. About a million people have also been displaced.
