The US State department alert on Tuesday stated, “On July 31, 2022, the United States conducted a precision counter terrorism strike in Afghanistan that killed Ayman al-Zawahiri, Osama bin Laden’s deputy and successor as leader of Al-Qa’ida. Al- Zawahiri was one of the masterminds of the attacks against the United States on September 11, 2001, and had continued to urge his followers to attack the United States.”

The alert further mentioned, “Following Al-Zawahiri’s death, supporters of Al- Qa’ida, or its affiliated terrorist organizations, may seek to attack U.S. facilities, personnel, or citizens.”

It stated that, “As terrorist attacks often occur without warning, U.S. citizens are strongly encouraged to maintain a high level of vigilance and practice good situational awareness when traveling abroad.”
