GAZA (AFP) - Hamas, the Islamist movement in de facto control of Gaza, vowed Saturday there would be no concessions to Israel, defying international attempts to broker a new ceasefire after fighting resumed.

"There will be no going back, the resistance will continue," Hamas spokesman Fawzy Barhum said in a statement. "The occupier's intransigence will get it nowhere and we will make no concessions on the demands of our people."
