During the raids in Rafah city, two tunnels were also discovered and destroyed, military spokesperson Colonel Tamer el-Refa'e said in a statement.
Takfiri is a term for hardline Sunni Muslims who see other Muslims as infidels, often as a justification for attacking them.
Egypt's North Sinai has witnessed many terrorists attacks since the January 2011 revolution that toppled the ex-president Hosni Mubarak.
The attacks, mainly targeting police and military, increased after the ouster of Islamist ex-president Mohamed Morsi in 2013 by military following massive protests against his rule.
The security forces have arrested suspects and demolished houses that belong to terrorists, including those facilitating tunnels leading to the Gaza Strip.
