The UN is starting the largest-ever polio vaccination campaign in the Middle East after an outbreak of the disease was detected in Syria.
The UN plans to immunise more than 20 million children in seven countries, including Lebanon.
While no cases of polio have been reported in Lebanon, half of the country's 800,000 Syrian refugees are children, and many have not been vaccinated against polio since they arrived.
