(JTA) — The U.S. under secretary of state for public diplomacy and public affairs published and then removed a tweet with a hashtag in support of Gaza.

Rick Stengel used the hashtag #UnitedForGaza in a tweet published late Saturday night calling for an international investigation into the crash of a Malaysian Airlines flight earlier this week in eastern Ukraine.

Hours later, on Sunday, Stengel removed the tweet and replaced it with a similar tweet using the hashtag #unitedforukraine.

Stengel added a tweet that read, “Earlier tweet with wrong hashtag was a mistake. My bad.”
