As reported in HAARETZ, the UN said on yesterday it had halted work on all but one of its 20 Gaza building projects as a result of an Israeli ban on importing building materials into the Palestinian enclave.

"Israel imposed the ban after discovering on October 13 a 2.5-kilometer (1.5-mile) tunnel which it said militants planned to use for attacks inside its territory. Islamist Hamas, which has run the Gaza Strip since 2007, claimed it dug the tunnel.

We are in now in the fourth week (in which) we are not allowed to bring in construction material, Robert Turner, director of Gaza operations for the United Nations Relief and Works Agency, said."
