The United States and Israel worked together to track and kill a senior al-Qaida operative in Iran earlier this year, a bold intelligence operation by the two allied nations that came as the Trump administration was ramping up pressure on Tehran. Four current and former U.S. officials said Abu Mohammed al-Masri, al-Qaida’s No. 2, was killed by assassins in the Iranian capital in August. The U.S. provided intelligence to the Israelis on where they could find al-Masri and the alias he was using at the time, while Israeli agents carried out the killing, according to two of the officials.
