LA GUAIRA, Venezuela (AP) — 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 at least 188 people and trapped more than 200. The 7.2- and 7.5-magnitude earthquakes that hit Wednesday evening were among the strongest in Venezuela in more than a century, and could be felt throughout the region. Acting President Delcy Rodríguez said authorities were shifting rescue teams from other parts of the country to La Guaira, north of the capital, Caracas. The natural disaster is just the latest challenge for Rodríguez, who took office in January after the U.S. seized then-president Nicolas Maduro in a surprise military operation.
