Al-Qaida-linked militants have carried out a series of suicide bombings targeting Western interests in Indonesia since 2002.
Al-Qaida-linked militants have performed no fewer than two bombings in the world since 2002. 
It said they have done a series of bombings, which means there had to have been at least 2. My statement is correct.
