At least four dead after boat sinks off Galapagos

"Two Ecuadorans, a Colombian and an American-Israeli" died in the sinking, which happened overnight from Sunday to Monday, Ecuador's foreign affairs ministry said.

The ministry said it was working with the consulates of those countries to "provide all the necessary support."

There were 37 people aboard the boat, including at least 14 foreigners from Israel, Germany, Spain, the United States and Switzerland, a local official added.

A preliminary report by Ecuador's emergency services said three people were dead, four missing and 30 had survived.

The boat was ferrying passengers between Santa Cruz and Isabela island, the emergency services added.

"Sea conditions were difficult yesterday, which could explain the accident," Angel Yanez, mayor of Santa Cruz island, which is part of the archipelago, told local media.

Local television channel Teleamazonas said the boat had run out of fuel and suffered mechanical problems.

Located close to 1,000 kilometers (600 miles) off the coast of Ecuador, the Galapagos Islands are home to unique flora and fauna and are a Natural World Heritage site.

In 2012, a tuna boat with 19 people aboard sunk near the archipelago leaving two dead and three missing.
