RNA - In a statement, the Israeli army announced that the individuals had been detained for "suspected involvement in popular hostile activities", Daily Sabah reported.
It, however, did not elaborate on the nature of these alleged "activities".
Among those detained was the brother of Palestinian resistance icon Ahed al-Tamimi, according to his mother.
"An Israeli force raided our home in the village of Nabi Sali near Ramallah and arrested my son Mohamed," Nariman al-Tamimi told Anadolu Agency, adding, "By arresting my son, the Israeli army is trying to break the will of our family."
A video footage posted on the mother's Facebook page showed Israeli forces surrounding the son as his sister Ahed al-Tamimi was shouting at soldiers.
Al-Tamimi's sister has already been in Israeli custody for several months now.
It remains unclear the reason behind the arrest and the Israeli army has yet to issue an official statement.
In late July, Israeli authorities released Ahed al-Tamimi and her mother after both had served eight months behind bars. The 17-year-old was arrested in late 2017 and was later slapped with an eight-month jail term for "attacking" an Israeli soldier.
Also, the Israeli military will impose a full closure of the occupied West Bank and the Gaza Strip during Tuesday's general election. The closure will be applied Monday midnight.
"According to the security situation evaluation and directives of the political level, total closure will be imposed in the areas of the West Bank and the terminals of the Gaza Strip on April 9," the army stated in a statement.
According to the military, the Kerem Shalom commercial crossing and Beit Hanoun (Erez) crossing with the Gaza Strip will be closed.
In the West Bank, Israel-issued work permits for Palestinian workers will be frozen, it added.
The right-wing Likud party, which is led by Prime Minister Benjamin Netanyahu, and Blue and White political alliance led by Benny Gantz are considered the main rivals in the polls to elect members of Knesset (Israel's parliament).
