UN finds second black box of Air Algerie jet
The UN peacekeeping mission in Mali said Saturday that its experts found the second black box of the Air Algerie plane that fell from the sky and disintegrated in remote northern Mali, killing all 118 people onboard.

The Burkina Faso government has flown three family members of those killed aboard the jet to the site in Mali where debris from the plane and the remains of passengers are scattered, said spokesman Victorien Sawadogo.
A government helicopter on Saturday morning transported the family members - from France, Lebanon and Burkina Faso - so they could view the results of the air disaster, he said. A psychologist is accompanying them and a second flight to the site was planned later Saturday, he said.
Burkina Faso President Blaise Compaore will meet with other family members Saturday afternoon, said the spokesman.
In Paris, French President Francois Hollande was meeting on Saturday with families of victims. Nearly half of the victims were French.
Spanish and Algerian officials flew to Burkina Faso Saturday to express their condolences.
"We send a message of condolences, sympathy, solidarity and availability to the people of Burkina Faso," Amar Ghoule, the Algerian minister of transportation and special envoy of president Aziz Bouteflika, told journalists after meeting with Compaore.
The Spanish ambassador in Burkina Fernando Maran also expressed "the will of the Spanish government to collaborate with Burkina Faso and other countries by making available all technical and human means that they have." All six crew members of flight AH 5017 were Spanish.
