A suicide attack is an attack in which the attacker or attackers intend to kill others and intend to die in the process (see suicide). In a suicide attack in the strict sense the attacker dies by the attack itself, for example in an explosion or crash caused by the attacker.
A suicide attack always has just one attacker.
I summarized a sentence. That is what made it difficult.
