From Fifteen Smuggling Tunnels Currently Active in Gaza:
Palestinian and Israeli security sources believe there are approximately 15 active tunnels in southern Gaza between the PA and Egypt being used by smugglers to move arms and people. The tunnels are controlled by powerful clans who consider them a lucrative source of income. Palestinians wanted for criminal activities are using the tunnels to escape abroad. In some cases, criminals in custody manage to escape with the help of their jailers.
