lagoon

The land is brown, the seasonal lagoon has dried up, and no one is out walking.

Elegant terns cried and circled in the distance, and pelicans flew from the ocean to the lagoon, so close overhead sometimes I could hear the flapping of their heavy wings.

Over the last week, they have tracked the birds on a digital map crossing Mexico, headed for Andean lagoons in Ecuador and Bolivia.

"When we got there, there was like a lagoon, blue, crystal clear water. We saw loads of caves, and then we actually found the surprise, a hidden waterfall," explained Charlie.

At least five people were killed and two bodies were found in the lagoons north of central Lomé, though whether they had drowned while fleeing arrest or been deliberately killed was unclear.
