Former Soviet republics have one of the world’s worst air traffic safety records.
Al Jazeera’s correspondent in Beirut, Rula Amin, said search-and-rescue efforts were being hampered by adverse weather conditions.
“The ships trying to help do not have an easy task .. the weather is stormy, with strong winds, heavy rains and high waves,” Amin said.
In the past two days, many parts of Lebanon have suffered harsh wintry storms that have caused heavy flooding and damage in some parts of the country.
UN peacekeepers based in Lebanon have joined the search.
“[The crash] site has been identified three and a half kilometres west of the [coastal] village of Naameh,” Ghazi Aridi, the Lebanese transport minister, said.
The aircraft carried 54 Lebanese nationals, 22 Ethiopians, as well as Iraqi, Syrian, British and French nationals, he said.
Thousands of Ethiopians work as domestic helpers in Lebanon.
There were also several dual nationals including one British-Lebanese, one Canadian-Lebanese and a Russian-Lebanese.

The 737 is the world’s best-selling commercial passenger aircraft and more than 6,000 have been sold or ordered since the aircraft was first introduced in 1967.
The Ethiopian News Agency in Addis Ababa said Ethiopian Airlines had sent a team to Beirut to investigate the crash.
