The entire European Union seeks the establishment of a Palestinian state, AFP cited the EU's new foreign affairs chief Federica Mogherini as saying Saturday. During a visit in Gaza, Mogherini stressed that the residents of the coastal enclave along with the rest of the world "cannot afford" another war involving the Strip. "We cannot just sit and wait. If we sit and wait it will go on for another 40 years. We have to have action now," AFP quoted her as saying.
