More than 100 health workers died in Libya in the aftermath of the floods last month, the World Health Organization (WHO) has said.

They were among the 4,000 people who had so far been confirmed dead, it said, adding that more than 8,500 were still missing.

"These 101 doctors, nurses and paramedics who lost their lives are not only missed by their families and loved ones; the whole community is affected by their departure and certainly the health sector in eastern Libya and beyond will be hit hard," said WHO Representative in Libya Dr Ahmed Zouiten in a tribute to the health workers.

The disaster happened after two dams that were poorly maintained amid years of conflict in the country burst under the pressure of torrential rains from Storm Daniel.

Entire neighbourhoods disappeared into the sea as the water hit eastern Libya, including the worst-hit city of Derna.
