Two boats loaded with migrants reached the Canary Islands late on Sunday as rescuers kept searching for 48 missing from an earlier sea wreck that may be the deadliest such accident for 30 years in the Spanish archipelago.

A makeshift vessel carrying 81 migrants reached Tenerife, the Canaries’ largest island, emergency services said on Sunday evening.

Another migrant boat reached the second largest Canary island, Fuerteventura. The emergency services did not specify the number of migrants on that boat. A third boat containing some 80 migrants was nearing the smallest island of El Hierro.

The two crossings followed a disastrous sinking of a migrant boat at the weekend that killed at least nine people and left at least 48 missing, including one under 18 years old, rescue services said. Rescuers were able to pick up 27 of 84 migrants who were trying to reach Spanish shores from West Africa.
