The death toll from devastating floods in the eastern Libyan city of Derna has risen to 5,300, the country’s official news agency reported earlier.

In a statement, the interior ministry of the government appointed by the House of Representatives in eastern Libya said thousands of people were still missing.

“Local rescue teams are continuing the search for missing people,” said Mohamed Abolmosa, the ministry’s spokesman, and called for “international intervention to help rescue efforts.”

On Monday, Libya’s Presidency Council appealed to neighboring countries and international aid groups to come together in flood-affected areas in the eastern region.

Other cities and towns affected by the weekend’s devastation include Benghazi, Bayda, Al Marj and Soussa.

Abdul Hamid Dbeibeh, head of Libya’s Tripoli-based unity government, declared all areas affected by the deadly floods disaster zones and declared three days of national mourning.
