Washington, Ramadan 24, 1435, Jul 21, 2014, SPA -- US President Barack Obama says the international community must focus on bringing an end to violence in Gaza amid a rising number of Palestinian and Israeli deaths, dpa reported. Obama points to Israel's right to defend itself against rocket and tunnel attacks by Hamas, but says the US has "serious concerns" about the rising death toll and will work to seek an immediate cessation of hostilities.
