UN officials are calling on Israel to end the blockade of the Gaza Strip. They\'re warning that the situation in the Palestinian territory may get even worse. The head of the UN agency for Palestinian refugees says the Israeli blockade has paralyzed Gaza\'s construction industry. Robert Turner also said that the demolition of tunnels used by Gazans to transfer goods and construction materials to the enclave has put U-N projects on hold. This, after Egyptian authorities also stepped up the destruction of the tunnels in recent months. Meanwhile, another U-N official, James Rawley has also waned about the humanitarian situation in the Palestinian territory over a lack of fuel there. Gaza\'s fuel crisis has led to the closure of its main power plant in recent months. Israel imposed its all-out land, aerial, and naval blockade on Gaza in June 2007 after the victory of Hamas in elections there. Show Less >>
