A total of 112 Syrians, including entire families, died in flash flooding that hit Libya's eastern city of Derna last week, said the Syrian Observatory for Human Rights war monitor (SOHR).
Libya hosts a huge Syrian diaspora and is also considered a launchpad for migrants from Syria and other countries hoping to reach Europe by sea on crowded and dilapidated boats.
"In total, 112 Syrians were killed in the flood and more than 100 are still missing," said the Observatory.
The flooding has killed nearly 3,300 people and left thousands more missing.
"I lost two nephews, their wives, and six of their children" including a six-month-old baby, said Syrian construction worker Khaled Ali, 37.
His nephews Hadi and Mahmoud had taken refuge in Lebanon after Syria's war erupted in 2011, but they later fled to Libya after Lebanon’s economy started to collapse.
"We fled from one crisis to another," said Ali who hails from Daraa province. "This is our fate."
Ibrahim Qalaaji, 46, held a funeral in Damascus for eight relatives, including his brother Mohammed and his wife and six children.
"A doctor there told us my brother and his wife had died, but there is no trace of the rest of the family," he said.
His surviving brother Shadi held on to a mosque's minaret as the waters hurled people towards him.
Shadi lost all his belongings, including identification papers, in the disaster, Qalaaji said.
"He has no past, no present, no future."
