From a New York Times story by Steven Lee Myers and Sheera Frenkel headlined “In a Worldwide War of Words, Russia, China, and Iran Back Hamas”:

The conflict between Israel and Hamas is fast becoming a world war online.

Iran, Russia and, to a lesser degree, China have used state media and the world’s major social networking platforms to support Hamas and undercut Israel, while denigrating Israel’s principal ally, the United States.

Iran’s proxies in Lebanon, Syria and Iraq have also joined the fight online, along with extremist groups, like Al Qaeda and the Islamic State, that were previously at odds with Hamas.
