Two explosions hit Myanmar's largest city on Tuesday evening, witnesses said, but no casualties were reported. An official said it was not immediately clear what caused the blasts, but that there were no casualties. He spoke on condition of anonymity as he was not authorized to release information. Witnesses said the first blast took place at about 9:40 p.m. at a small park in western Yangon near Myeinigone junction, a busy area with a bus terminal. They said the second, shortly after 11 p.m., occurred by a bus stop near another park close to Kamayut junction, another busy thoroughfare.
