Drone rescue plan for dogs trapped by La Palma volcano

Crew prepare for mission to evacuate four dogs stranded on Spanish island between rivers of red-hot lava

An unprecedented drone operation is being prepared to rescue four dogs stranded for weeks between rivers of red-hot lava streaming from an erupting volcano on the Spanish island of La Palma.

The emaciated dogs are stranded in two empty water tanks in the town of Todoque, flanked by slow-moving lava flows from the Cumbre Vieja volcano that erupted on 19 September .
