Sheikh Mohammed bin Rashid, the Vice President and Ruler of Dubai, has ordered a third emergency delivery of vital aid for flood-hit Jordan in less than 48 hours.
Sheikh Mohammed approved a move to transport 85 tonnes of supplies, including relief items donated by the UAE Red Crescent, on a Boeing 747 jumbo jet.
It comes after 58 tonnes of health, food and sanitation supplies were sent to the country from the UAE in a Boeing 747 from Dubai's royal fleet and a C-130 Hercules transport carrier on Monday.
Flash floods have swamped Jordan in recent days, leaving a trail of devastation.
Thirteen people have died and evacuation orders forced up to 4,000 tourists to leave ancient city Petra.
Torrential rains also caused problems in port city Aqaba.

The flooding comes two weeks after more than 20 people drowned in floods in the Dead Sea area.
The Dubai operation was co-ordinated by Princess Haya, chairwoman of International Humanitarian City, a logistics centre in the Dubai desert. It was also co-ordinated with the National Crisis Centre in Jordan.
Princess Haya is a Jordanian royal family member known for her humanitarian work.
The airlift to Jordan is the latest in series of humanitarian missions made by Dubai. Sheikh Mohammed has also ordered scores of airlifts to Myanmar to help Rohingya refugees.
The 58 tonnes of relief items donated earlier by Sheikh Mohammed have already been distributed to those in need by the National Crisis Centre, under the guidance of Prince Ali bin Al Hussein, who received the flights and then co-ordinated emergency relief efforts on the ground.
