Syria's state TV says 43 Syrian citizens were killed in this week's blast in Beirut.
The TV quotes the Syrian embassy in Lebanon as saying that the number is not final as search operations for dozens of missing are still ongoing.
Lebanon is home to more than a million Syrians many of them refugees who fled civil war in their country.
A Lebanese health ministry official said on Saturday that the blast killed 154 people, including 21 bodies who have not been identified. He added that 45 people are still missing.
