MADRID—Authorities on the Spanish island of La Palma ordered residents of three coastal towns to stay indoors on Monday after a new stream of lava crashed into the ocean, sending thick clouds of potentially toxic gases high into the sky.
A third tongue of lava from the Cumbre Vieja volcano, which has been erupting for two months, reached the water around midday (12:00 GMT) a few kilometres north of where two previous flows hit the sea.
