Al-Jazeera Video: Ancient Gaza tunnels discovered

"Archaeologists digging at a site on Gaza's border with Egypt have discovered ancient tunnels in the same area as today's smuggling tunnels.

They are believed to be a part of a hidden city that is estimated to be over two thousand years old. However, the excavation work is complicated by the blockade of Gaza as there is the constant risk of being caught in the way of an Israeli rocket strike on a modern tunnel.

There is also a shortage of funding for adequate excavation and looters are a constant threat.
