The smells of grilled cheese and cooked corn waft over the protesters in the Lebanese capital - with daily crowds filling the the capital's main squares, the movement has been a boon for street vendors. Ibrahim is a plasterer by trade, but when he saw crowds flocking by the tens of thousands to Beirut's Martyrs' Square to protest against government corruption and incompetence, he knew it was not an opportunity to be missed. One day, he's selling "kaak", a round, savoury Lebanese bread covered in sesame seeds. The next, it's corn on the cob or small trays of lupin beans dressed with cumin and lemon juice. "It's better than being out of work," the stocky 27-year-old said. Times have been tough for many months, he said, with the country hit by an economic crisis that has not spared the construction sector.
