In a food processor, combine the chickpeas, parsley, cilantro, garlic, onion, cumin, coriander, paprika, turmeric, lemon juice, olive oil, salt, and pepper. Pulse until the mixture is finely chopped but not pureed.
Add the flour and pulse again until the mixture holds together when pressed.
Form the mixture into small balls or patties.
Heat olive oil in a frying pan over medium heat and fry the falafel in batches for 2-3 minutes on each side, or until golden and crispy.
For the yogurt sauce, combine the yogurt, lemon juice, cumin, and salt in a small bowl.
Serve the falafel warm with the yogurt dipping sauce on the side.
