Venezuela: Tens of thousands still missing after twin earthquakes

Foreign search and rescue teams have arrived in Venezuela to assist with the desperate and slow-moving search for survivors after the country's most powerful earthquake in more than a century. The death toll nearly doubled on Thursday to 920, but authorities warn the final number is expected to be far higher, with tens of thousands of people still reported missing. Frustration has also been growing over the official response and the limited resources available for rescue efforts.
