Twenty-nine Hamas operatives were arrested in the West Bank city of Nablus on Tuesday night, in a joint operation by the Shin Bet security service, IDF and Israel Police.

According to a Shin Bet statement, some of the detainees are high-ranking Hamas members and have been incarcerated in Israeli prisons in the past. The detainees were taken for questioning by the Shin Bet.

Security services said the unusually large sweep comes in light of Hamas' increased activity in the area. The Shin Bet said ther suspects operated "with funding and guidance from Hamas headquarters outside the country."

In a separate raid, three Palestinians were also arrested in the West Bank Tuesday night.
