Two Palestinian workers went missing as a tunnel at the southern Gaza Strip borders collapsed on them on Tuesday.
Palestinian media sources said that the tunnel is located at the Yibna camp for Palestinian refugees in Rafah city.

When the tunnel collapsed six workers got trapped in it. Later four managed to get out from the Egyptian side while two are still missing, local sources reported.

Since Israel started its siege on the Gaza Strip back on June 2007, the tunnels at the borders with Egypt became the main sources of much needed supplies for the 1.5 million Palestinians living in the coastal enclave.
