One United States citizen was killed and several more were wounded in the Lebanon blast that devastated its capital this week.

The explosion rocked the port area of Beirut and has killed at least 157 people and wounded 5,000 more, a number that has steadily climbed since Tuesday. A State Department spokesperson told the Washington Examiner on Thursday that it is still working to determine if more people from the U.S. were killed or injured in the incident. The U.S. has not yet released the names of those affected.
