Le bilan du glissement de terrain qui a dévasté un village de l'Etate de Washington, près de Seattle, s'est à nouveau alourdi mardi pour atteindre 24 morts. Here " à nouveau" is put between "s'est" and the verb "alourdi". When the verb is used as perfect tense, how about the positions of the auxiliary verb and the verb? Is there any rule that the verb and auxiliary verb should be close together? Or any word could be put between the auxilary verb and the verb? Just like "à nouveau" is put between "s'est" and the verb "alourdi". Thanks!
