The killings in San Bernardino, California, on Wednesday mark the sixth successful attack motivated by Islamic extremism in America since September 11, 2001, according to a Washington Free Beaconanalysis.
The analysis counts attacks conducted by people espousing a radical Islamist ideology, and which resulted in at least one murder. The six incidents were carried out across the country from Boston to Tennessee to California. The terrorists involved employed either firearms, explosives, or a combination of the two during their attacks. Five of the six attacks have occurred since 2009.
The first of the post-9/11 attacks on American soil occurred at Los Angeles International Airport on July 4th, 2002, where an Egyptian national, Hesham Mohamed Hadayet, murdered two Israelis and injured four others at the El Al ticket counter before being killed by security.
