The IDF, Border Police and Shin Bet arrested a member of the Lion's Den terrorist group in Nablus on Friday.
The terrorist, identified as Ahmad Masri, was an aid to Ibrahim Nabulsi, a leader of the Lion's Den who was killed a few months ago in a clash with Israeli forces.
Masri had taken part in recent terrorist activities. During the arrest, the Israeli forces seized a firearm and magazines Masri was holding.
