Idk about suicide bombers, but I do know that the deadliest act of aviation terrorism up till 9/11 was at the hands of Canadian Sihk terrorists on behalf of the Sihk militant group Babbar Khalsa. Not to mention, there have been instances of violence from Buddhist nationalists in Sri Lanka against Muslim minorities. There are also many, many, many, many instances of Christian terrorism, and not just in the United States. The Lords Resistance Army has been terrorizing Africa since the 1980s.
There are currently no religions that do not have extremists that employ violence. Religion itself is violence, as it is a means of control and dominance. There are no good religions, and no peaceful ones.
