JERUSALEM — In an effort to appeal to Palestinians ahead of hotly contested elections, the party of President Mahmoud Abbas listed one of its main achievements as having “killed 11,000 Israelis.”

The party, Fatah, made the incendiary claim on Tuesday in an Arabic-language post on one of its official Facebook pages.

“For the argumentative … the ignorant … And for those who do not know history,” begins the Facebook post, “The Fatah movement killed 11,000 Israelis.”

Fatah also claimed to have “offered 170,000 martyrs,” and hundreds of its followers, it said, were in “Israeli occupation jails.” By Thursday the post had been shared 30 times and liked 163 times.
