Aid was trickling into eastern Libya on Wednesday, where more than 5,000 people have died in recent days from catastrophic flooding.
But with roads and bridges damaged and cut off, access to the hardest-hit city of Derna on the Mediterranean coast remained a major hurdle to bringing in help, according to international aid groups.
Thousands of people are believed to still be missing, meaning the death toll was likely to rise further in the hours and days ahead.
The flooding hit after heavy rains burst through two dams near Derna, a city of nearly 100,000 people.
The Derna City Council has called for the opening of a maritime passageway to the city and for urgent international intervention.
