At least 60 are still missing, and about 7,000 are in shelters, Interior Minister Humberto Centeno told a news conference.

Authorities had to use helicopters to reach some of the most severely affected townships, Centeno added.

In the capital of San Salvador, authorities reported 61 dead including a family of four - two adults and two children - who were killed when a mudslide buried their home yesterday morning, Red Cross spokesman Carlos Lopez Mendoza reported.

Central San Vicente province was also hit hard, with 23 killed there.

The rest died in other parts of the country, Vice Interior Minister Ernesto Zelayandia said. Most of the victims were buried by slides or carried away by raging rivers.

"We have been through disaster zones, including a fly-over of the area of Verapaz (in San Vicente)," Centeno said. "It is a real tragedy there," with at least 60 people unaccounted for, he said.

Red Cross spokesman Carlos Lopez said a river in Verapaz overflowed its banks and swamped 300 homes.

The rains unleashed massive rock slides from the Chichontepec volcano that buried several houses, Verapaz Mayor Antonio Cerritos told Radio Nacional.

Dave Roberts, a Navy hurricane specialist at the U.S. National Hurricane Center in Miami, said Hurricane Ida's presence in the western Caribbean may have played a role in drawing a Pacific low-pressure system toward El Salvador, causing the rains.
