Troops set charges to destroy the homes of Hussam Kawasme and Amar Abu Aysha in the southern West Bank before dawn and sealed off the home of a third suspect, Marwan Kawasme, the army said.
Israel accuses Hamas Islamist militants of the abduction and killing of Jewish seminary students Gil-Ad Shaer, Naftali Fraenkel and Eyal Yifrah, who went missing on June 12 and were discovered dead a couple of weeks later in the West Bank.
Hamas has neither confirmed nor denied the accusations.
