U.S., Israel worked together to track and kill al-Qaida No. 2

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.
