BANGKOK (AP) — Airstrikes by Myanmar’s military on Tuesday killed as many as 100 people, including many children, who were attending a ceremony held by opponents of army rule, said a witness, a member of a local pro-democracy group and independent media. ”’This heinous act by the terrorist military is yet another example of their indiscriminate use of extreme force against innocent civilians, constituting a war crime,” the opposition National Unity Government said in a statement. Resistance forces have been able to prevent the military from taking firm control of large areas of the country, but have a great disadvantage in weapons, particularly in countering air attacks
