Mediterranean rescue

Migrants are rescued by members of a Spanish nonprofit in waters near Libya during a mission on May 6. The aid group Proactiva Open Arms found the 105 migrants, from Bangladesh, Egypt, Libya, Nigeria and other countries, drifting at sea in a motorless boat.

Each year, tens of thousands of migrants attempt to reach Spain and other southern European countries by crossing the Mediterranean in smugglers' boats. Most of the vessels are unfit for open water, and thousands of migrants drown each year.

Advancing lava

Lava advances along a street near a fissure in Leilani Estates, on Kilauea Volcano's lower East Rift Zone, on Hawaii on May 5.

The volcano, which has been spitting and sputtering lava for a week, has destroyed more than two dozen homes and threatened a geothermal plant. The added threat of an explosive eruption could ground planes at one of the Big Island's two major airports and pose other dangers. The national park around the volcano announced that it would close because of the risks.
