Venezuelans searched for survivors beneath collapsed buildings and rescue teams raced to northern areas rocked by a pair of powerful earthquakes that officials say killed around 235 people and left at least 4,300 people injured. The 7.2- and 7.5-magnitude earthquakes that hit Wednesday evening were among the strongest in Venezuela in more than a century. The quakes could be felt throughout the region. Acting President Delcy RodrÃguez says authorities were shifting rescue teams from other parts of the country to La Guaira, north of the capital Caracas. The natural disaster is the latest challenge for RodrÃguez, who took office in January after the U.S. seized then-president Nicolas Maduro in a surprise military operation.
