The city of San Antonio de Areco, in northern Buenos Aires Province, was hit particularly hard, with 90 blocks underwater, Gov. Daniel Scioli told the state-run Telam news agency. He said the flooding was unlike any he had seen, and it caught the area by surprise.

“The ambulance was underwater. So were the doctors’ cars,” Scioli said. “Water even reached the Guiraldes Museum, with its rich heritage.”

Alejandro Delgado Morales, director of press and information for Buenos Aires Province, told CNN there had been two deaths but could not provide further details.

Gay rights activists Jose Maria Di Bello and Alex Freyre were married in Ushuaia, the capital of Argentina’s Tierra del Fuego state, exchanging rings at civil ceremony witnessed by state and federal officials.

“My knees didn’t stop shaking,” said the 41-year-old Di Bello. “We are the first gay couple in Latin America to marry.”

The slim, dark-haired couple previously tried to marry in the Argentine capital of Buenos Aires but were thwarted by city officials citing conflicting judicial rulings. Argentina’s Constitution is silent on whether marriage must be between a man and a woman, effectively leaving the matter to provincial officials.

Gustavo Anibal Giraldo was being transferred to a court hearing when three gunmen on motorbikes attacked his eight-man escort.

One guard was killed and another hurt as the rebels overwhelmed the convoy in the north-eastern city of Arauca.

The ELN commander then fled on the back of a waiting motorcycle.

Police found a van and two motorcycles abandoned near the Venezuelan border shortly after Wednesday’s attack.
