Cambodia has conducted attacks at multiple locations in violation of a ceasefire deal, a Thai army spokesman said on Tuesday, a day after the two neighbours said they would stop all fighting starting at midnight.

Thai troops have retaliated proportionately in self defence, Major General Winthai Suvaree said in a statement.

The leaders of Thailand and Cambodia met in Malaysia on Monday and agreed to halt their deadliest conflict in more than a decade following five days of intense fighting that displaced over 300,000 people. (Reuters)
