A drone strike killed a leader of the al-Shabaab militant group in southern Somalia, US authorities have claimed.
Adnan Garaar was killed when the drone hit the vehicle he was travelling in on 12 March near Diinsoor, the Pentagon said in a statement.
Garaar, a top al-Shabaab official, was suspected of masterminding the 2013 attack on the Westgate shopping mall in Nairobi, Kenya, that killed 67.
He posed a major threat to the region and the international community and was connected to the West Gate Mall attack in Nairobi, Kenya. His death has dealt another significant blow to the al Shabaab terrorist organisation in Somalia.
Somali pirates have released four Thai hostages, who were captured while fishing in 2010, bringing to an end the longest-running international hostage drama in the Horn of Africa.
The four men were part of a Taiwanese flagged fishing vessel which was seized by pirates almost five years ago.
Of the original 24 person crew six died in captivity, 14 from Myanmar were released in 2011 and the remaining 4 were freed today.
Nicholas Kay, the UN Secretary General's Special Representative for Somalia said he was "grateful to see the longest-held hostages released from Somalia, and thank all those involved who made it happen,"
Somali pirates are still holding 26 crew from a vessel that was captured in 2012.
The incidents of piracy have been severely curtailed since 2010 following the creation of an international task force to combat piracy in the Indian Ocean.
