RIYADH, Saudi Arabia – Saudi health minister said Saturday that conjoined Palestinian twins flown to Riyadh from the Gaza Strip cannot be separated and do not have long to live. The two-week old twins, joined at the chest, overcame immense obstacles to make it out of the Gaza Strip including an Israeli blockade, rival Palestinian governments and a string of national holidays. Abdullah al-Rabeeah said in a statement Saturday that the girls Rital and Ritaj have a life threatening condition and similar cases in the past have not survived. Tests show the twins suffer from a bacterial chest infection and their hearts, livers and digestive tracks work in tandem. Saudi King Abdullah had agreed to pay for the operation and a special plane was chartered to fly them to Riyadh.
