During the raid, police also seized more than 50 grams of drugs suspected of being cocaine and heroin that were also intended for trafficking and distribution purposes.
This activity joins a long line of firearm and drug seizures carried out by the Israel Police every day, for the safety and well-being of the public.
The suspects are all in their 20s. They were detained for questioning at the police station, and then jailed.
On Wednesday, the Tel Aviv Magistrate's Court granted the police's request and extended their detention by five days.
