NEW: Explosion Hits Hotel in Myanmar's Main City 10/14/13
YANGON, Myanmar - Police in Myanmar say an explosion at one of the largest hotels in the main city Yangon and one American was wounded.
It was not immediately clear what caused the blast just around midnight at the Trader's Hotel on Tuesday in Yangon, or whether it was an accident.
A police officer on the scene who declined to be named says an American woman was slightly injured and taken to a Yangon hospital.
A U.S. Embassy official confirmed an American was injured.
Police in the Southeast Asian nation had earlier urged caution after several small bombs exploded in and around Myanmar's largest city in recent days, killing two people.
