Environmentalists call for investigation into suspected toxic algae in lake north of Rome.

Several dogs have reportedly died in recent days after drinking water at Lago Bracciano, a lake north of Rome, according to a press release by the Lazio branch of Ecoitaliasolidale.
The environmental group has appealed to the lake's authorities to investigate residents' claims that their dogs were poisoned as a result of the toxic algae cyanobacteria, alleged to be present in the water.
Lake Bracciano, an important source of potable water for Rome, was central to a dispute over water rationing between the capital and the Lazio region during the summer drought in 2017.
