More than 220 people have been killed and 843 injured after a tsunami hit coastal towns on Indonesia's Sunda Strait, government officials say. The tsunami waves struck at night without any warning, destroying hundreds of buildings. Officials say the tsunami may have been caused by undersea landslides after the Anak Krakatau volcano erupted. The Sunda Strait, between the islands of Java and Sumatra, connects the Java Sea to the Indian Ocean. Please subscribe HERE http://bit.ly/1rbfUog
