• Khaled Meshaal
In 1997 Mossad attempted an assassination of senior Hamas official Khaled Meshaal in Jordan, by spraying him with poison — but was forced by Jordan's outraged King Hussein to provide the antidote

Meshaal is now considered among the contenders to become the new leader of Hamas

Khaled Meshaal, tipped to be the new Hamas leader, became known around the world in 1997 after Israeli agents injected him with poison in a botched assassination attempt on a street outside his office in Amman, the Jordanian capital

The hit against a key senior figure of the Palestinian militant group, ordered by Israeli Prime Minister Benjamin Netanyahu, so enraged Jordan's then-King Hussein that he spoke of hanging the would-be killers and scrapping Jordan's peace treaty with Israel unless the antidote was handed over.

Israel did so, and also agreed to free Hamas leader Sheikh Ahmed Yassin, only to assassinate him seven years later in Gaza.
