Gazans have been living under siege for four years. After the closure of all crossing points from Egypt into Gaza, they were forced to dig tunnels under the border town of Rafah to provide a lifeline to their families. So far, Israeli air raids have killed over 400 Gazans working in these tunnels, even post-graduate students. Today, as digging develops and tunnels are now able to accommodate cars, working in them has become even more dangerous.
