A supposed ISIS flyer circulating on social networks has warned 18 writers and poets in Gaza against what it calls criticizing Islam, stating that ''apostates will be punished." In Ramallah, the Palestinian Authority responded by condemning the intimidation of Palestinian intellectuals, calling the threats a serious precedent. Hamas played down the incident. Gaza's interior minister, Yiad Bazam, denied that ISIS operates in any form in the Gaza Strip and that the threats are nothing more than ''pranks." He nonetheless assured that the Hamas secret services are monitoring the situation. The threats came after a similar text, signed by men claiming to be ISIS adherents, warned women in Gaza that they will not be allowed to walk in the streets without the hijab. Poet and women's rights activist Donia al-Amal Ismael received the first flyer via Facebook. It accused her and other writers of speaking ill of God and Islam, and threatened to slit their throats. Ismael expressed skepticism that ISIS is really behind the flyer: "I think that I must deal with this as a joke, to be strong." Israeli Prime Minister Benjamin Netanyahu has called Hamas and ISIS "brother organizations" and "branches of the same poisonous tree." (ANSAmed, NPR, Dec. 17)
