A Palestinian-American teenager is expected to appear in court in Israel later this week after nine months in detention without being charged.

Mohammed Ibrahim, who is 16 and lives in Florida, was arrested in February while on holiday in the Israeli-occupied West Bank for allegedly throwing stones at Jewish settlers, something he denies.

Last month, 27 Democratic US Senators and House members sent a letter to the US State Department, urging the Trump administration to do more to pressure Israel to release him.

In a statement, Israeli Prime Minister Benjamin Netanyahu's office said Mohammed had committed a "a serious potentially deadly crime" and that the court was proceeding under due process.

The teenager's family disagrees.
