BEIRUT, Lebanon (CNN) — An explosion just north of Beirut struck a U.S. Embassy vehicle Tuesday, a Western diplomatic source told CNN.
The source could not confirm Lebanese media reports of three deaths.
The blast appears to be the latest in a series of attacks against pro-Western, anti-Syrian targets in the Lebanese capital.
Most recently, an explosion in Beirut’s Christian suburb of Baabda killed Brig. Gen. Francois Al-Hajj, the head of operations for the Lebanese army, and his bodyguard on December 12.
Al-Hajj was believed to be a top candidate to take over as army commander in the event current commander Gen. Michel Suleiman was elected to replace Emile Lahoud as president.
Lebanon has been in the midst of a political crisis as pro- and anti-Syrian lawmakers in parliament are locked in a battle to elect a new president.
The nation has been without a president since November 23, when the pro-Syrian Lahoud stepped down at the end of his term.
In February 2005, the assassination of former Lebanese Prime Minister Rafik Hariri in Beirut sparked widespread protests that led to the ouster of Syrian forces from Lebanon.
