Sixty people survived after two boats with nearly 100 migrants capsized. The causes of the shipwrecks were not clear, Italian officials and U.N. agencies said. The death toll is likely to grow.

At least 26 people died in a migrant shipwreck on Wednesday off the southern Italian island of Lampedusa and 60 survivors were brought ashore, the coastguard said, warning more bodies could be missing as search operations continue.

There are 60 survivors from the perilous journey from Libya, but a UN agency says there could be more people missing.
