Pompeo on Friday morning said that the department had already blocked entry to ICC officials looking into alleged war crimes committed at U.S. detention facilities in Afghanistan.

“Don’t assume you’ll get a visa,” he said.

The ban extended to ICC cases against “allied personnel, including Israelis.” Israel was the only country mentioned as an example in the statement.

Pompeo said the Trump administration was also considering sanctioning officials pursuing ICC actions against the United States.

Why it matters: The Palestinian Authority has asked the ICC to open investigations into alleged Israeli war crimes since 2014, when the Palestinian government joined the international body, for Israeli actions in Gaza, the West Bank and eastern Jerusalem. This U.S. State Department move is a sharp rebuke of that concept — especially since the statement specifically mentions Israel in its text.

Neither the United States or Israel are members of the ICC, but ICC officials may be subject to arrest when they visit member nations.
