Rescue Efforts Underway After Tsunami Hit Indonesia Without Warning

Rescue crews are helping thousands of people who were injured or displaced after a tsunami struck the coasts of Java and Sumatra in Indonesia on Saturday night. Many residents did not receive any warning before the tsunami, which killed hundreds.

Volcanic activity on Indonesia's famous Anak Krakatau island triggered underwater landslides that caused the tsunami, officials say. Anak Krakatau emerged from the site of an 1883 eruption that killed tens of thousands of people and has drawn tourists from around the world.

At least 373 people have died, with 128 missing and nearly 1,500 wounded, according to Sutopo Purwo Nugroho, a spokesman for Indonesia's disaster management agency.

Crews continue to search for survivors while retrieving bodies from the wreckage with heavy machinery and their hands, Reuters reports.

The Red Cross has dispatched 22 ambulances and more than 100 volunteers to transport the injured. Blocked streets have hindered access to health centers in Pandeglang, on the island of Java, where Doctors Without Borders volunteers are helping to treat patients injured by the tsunami and falling rubble.
