( CNN ) -- Lebanese parliamentarian Antoine Ghanem was killed in a massive bombing in Beirut on Wednesday, according to Lebanese Broadcasting Corp., quoting a member of Ghanem's Phalange Party.
At least four other people were killed in the explosion, according to a high-ranking government official.
Red Cross officials told Lebanese Broadcasting Corp. that 20 people were wounded in the blast -- a huge fireball that damaged dozens of cars.
Nearby buildings were heavily damaged and broken glass littered the street, near the Librairie Antoine, a bookstore.
Three months ago, anti-Syrian Parliament member Walid Eido was killed along with nine others -- including his son and two bodyguards -- in a huge explosion in western Beirut.
President Bush said Eido's killing in June was part of "a clear pattern of assassinations and attempted assassinations in Lebanon since October 2004."
Most notorious was the February 2005 assassination of former Lebanese Prime Minister Rafik Hariri, whose killing in Beirut sparked widespread protests that led to the ouster of Syrian forces from Lebanon.
Syria has denied any involvement in the killings
