This poll is not going to be accurate because you have worded it so. Everyone knows there are tunnels there because Israel dug them in particular there before leaving occupation in 2006. The real questions should be if they are connected, serving as a logistics hub, or used for storage of weapons. Even then, that's a completely different question on if it was justified to take the hospital in the way they did as opposed to just bombing it and of the certainty of the intelligence played into the decision making there.
