A strong earthquake in Costa Rica has left at least eight people dead.
The quake measured 6.2 on the Richter scale and hit early Saturday during the Ibero-American summit in San Jose, which was attended by leaders from some 20 countries. None of the participants was hurt.
Costa Rican officials say most of the eight deaths were the result of heart attacks.
The earthquake destroyed hundreds of homes and damaged roads and highways.
The U.S. Geological survey says the quake was centered about 40 kilometers south of San Jose.
