US to Investigate Beirut Blast, Diplomat Says VOA News U.S. senior diplomat David Hale said in Beirut Thursday the U.S. Federal Bureau of Investigation will join Lebanese and international investigators in a probe into the recent explosion in Lebanon's capital city that killed scores of people and injured thousands of others. During a visit to one of Beirut's neighborhoods that was heavily damaged by the blast, the U.S. undersecretary for political affairs said the FBI would join the investigation at the invitation of Lebanese authorities. Hale said the FBI's participation in the probe is one way the U.S. is helping the country cope with the aftermath of the massive explosion. Hale is scheduled to meet with Lebanese officials over the next two days. The U.S. Embassy said Hale was to emphasize the need for reform when he meets with officials. .
