Myanmar and rebels on Monday resumed ceasefire talks that were postponed in November when the army shelled a Kachin rebel training camp in the north of the country, killing 23, dpa reported. Top-level representatives were not due to attend the talks in Yangon, which were expected to focus on the shelling, an official said. "Unless there is a good explanation for the attack, it might be very difficult to move forwards on the peace talks," said Khun Okka, member of Nationwide Ceasefire Coordination Team (NCCT). The NCCT, an umbrella group of several ethnic armed factions, postponed the seventh round of talks planned for November after the army's assault on the training camp near the border town of Laiza, the headquarter of Kachin Independent Army (KIA) on 19 November. The military says the artillery shell was just a warning shot which inadvertently hit the camp.
