Italy probes deaths of 26 Nigerian women from migrant boats
Italian prosecutors are investigating the deaths of 26 Nigerian women - most of them teenagers - whose bodies were recovered at sea.
There are suspicions that they may have been sexually abused and murdered as they attempted to cross the Mediterranean.
Five migrants are being questioned in the southern port of Salerno.
A Spanish warship, Cantabria, docked there carrying 375 migrants and the dead women, following several rescues.
Twenty-three of the dead women had been on a rubber boat with 64 other people.
Italian media report that the women's bodies are being kept in a refrigerated section of the warship. Most of them were aged 14-18.
Most of the 375 survivors brought to Salerno were sub-Saharan Africans, from Nigeria, Senegal, Ghana, The Gambia and Sudan, the daily La Repubblica reports.
Among them were 90 women - eight of them pregnant - and 52 children.
There were also some Libyan men and women on board.
People-smuggling gangs charge each migrant about $6,000 (£4,578) to get to Italy, $4,000 of which is for the trans-Saharan journey to Libya, according to the Italian aid group L'Abbraccio.
Many migrants have reported violence, including torture and sexual abuse, by the gangs.

Of them, 111,552 (nearly 75%) came via the Central Mediterranean route to Italy. The number who died on that route was 2,639, the IOM says.
The others arrived in Greece, Cyprus or Spain. The total is less than half the 335,158 who arrived in the same period of 2016.
Last year the total for Greece was higher than that for Italy.
A note on terminology: The BBC uses the term migrant to refer to all people on the move who have yet to complete the legal process of claiming asylum. This group includes people fleeing war-torn countries such as Syria, who are likely to be granted refugee status, as well as people who are seeking jobs and better lives, who governments are likely to rule are economic migrants.
