The United Nations Children's Fund (UNICEF) on Monday expressed concern over the shortage of water in Libya, which threatens millions of people, especially children.

"Over four million people, including 1.5 million children, will face imminent water problems if immediate solutions are not found and implemented," UNICEF said in a statement.

The statement explained that the prolonged crisis in the country has impaired its water facilities.

"This is mainly attributed to the lack of required budgets for the purchase of equipment, operational materials and spare parts for regular maintenance. Suppliers are also struggling to open bank credits in hard currency to import equipment from outside the country," the statement said.

The UNICEF calls on the Libyan government and international organizations to prioritize the water supply in order to avoid a "humanitarian disaster," said UNICEF Special Representative in Libya, AbdulKadir Musse.
