An Arab youth was killed when a tunnel linking Egypt to Gaza collapsed on Saturday, Arab medical sources said.

“Mussa Ghonaim, 26 years old, was killed in the tunnel collapse south of the town of Rafah,” the sources said, according to AFP.

In February, the Islamist terror movement Hamas, which governs Gaza, closed hundreds of tunnels used for smuggling in Rafah, which straddles the border between Egypt and the coastal enclave.

Hamas is making at least a million dollars a day in “tax” money from Gaza smugglers, a senior IDF officer said Monday. Colonel Wael Tafesh, who is a top IDF officer in the IDF’s coordination unit with the Palestinian Authority, said that Hamas provided “protection” to smugglers and collected payments for the service, and often used the smugglers to order goods for their own use.
