Can I use ”who” instead of ”with whom” ?

Before Brown spoke, the speaker of the parliament, Dalia Itzik, said it was unbelievable that 63 years after the Holocaust, "we are again facing the threat of extermination from the Iranians, with whom we have no conflict".
Update: 成句係我同佢冇衝突

佢 = Iranians ?
