ADDIS ABABA - One of the black boxes from an Ethiopian Airlines jet that crashed on January 25 off Lebanon's coast has been sent to France for analysis, a spokeswoman for the airline said Tuesday.

"We cannot say when we'll have news because it is a process and there is an investigation," Wogayehu Terefe told AFP.

Wogayehu said more bodies had been retrieved but said they still waiting for an exact figure. Twenty three bodies had been found by Sunday.

The Lebanese navy Sunday retrieved one of the two black boxes from the plane that was flying from Beirut to Addis Ababa with 90 people on board.

Flight ET409 crashed into the sea minutes after taking off from Beirut in the middle of a storm.

No survivors were found from Flight 409, and searchers have been struggling to recover bodies from the crash as most victims were believed to be still strapped to their seats.

The probe is being carried out by a Lebanese commission with support from a French body responsible for technical investigations into air accidents.

American and Ethiopian investigators are also involved.
