The death toll in El Salvador's earthquake has reached 255 with at least 2,261 reported injured
Among the victims were six kindergarten students and their 25-year-old teacher, killed when their parochial school collapsed in the small town of Candelaria, 25 miles east of the capital San Salvador.
The teacher, Anabel Chavez, was found with her arms around some of the children.
"The church and the school are literally flat on the ground," said Oswald Guerra, deputy commissioner of the national civil police.
The schoolchildren were between four and six, Mr Guerra said. He said another 40 children received leg and arm injuries.
Hardest-hit were the provinces of San Vicente, Cuscatlan and La Paz, in the centre, where at least 167 people were killed, the emergency committee said.
In Candelaria, at least 39 people were killed, 57 were injured and two were missing. A total of 1,300 houses were ruined and another 600 damaged.
Officials said the death toll could sharply increase due to numerous landslides that had blocked highways and prevented access to some communities. Flores said army brigades were working to rescue an unknown number of people buried in rural landslides.
