At least 43 people have reportedly been killed and 600 injured after a tsunami hit the coast around Indonesia's Sunda Strait, government officials say. According to the country's disaster management agency, the possible cause of the tsunami was undersea landslides after a volcano erupted. Dozens of buildings were also damaged. The Sunda Strait between the Indonesian islands of Java and Sumatra connects the Java Sea to the Indian Ocean. Footage posted on Twitter by the head of Indonesia's disaster management agency showed flooded streets and an overturned car during the aftermath of the tsunami.
