Israeli security forces on Wednesday night raided the Palestinian village of Qusra, near Shechem (Nablus) and arrested 20 Palestinians who are suspected of having been involved in a lynch attempt on a group of young Israeli hikers last Thursday and in the violent riots that ensued after the incident.

The Israeli army detained 35 Palestinians in overnight raids in the West Bank and East Jerusalem, a Palestinian NGO said on Thursday.

The joint operation in Qusra was conducted by the Israel Defense Forces, Israel Police, Shin Bet security service and the Defense Ministry's Coordinator of Government Activities in the Territories office, which acts as a liaison with Palestinians.

All the suspects were transferred to the Israel Police for questioning.

Several days later, a group of settlers who visited the area clashed with Palestinians.

Settlers plan to return to the cave Friday apparently for a bar mitzvah celebration, Haaretz reported, which may further inflame the situation.

While the Israeli government considers Jerusalem the country's capital, the US and the global community at large recognize Tel Aviv as Israel's capital city.

However, the spokesperson added that the trip had been coordinated and an email had been sent to the IDF regional headquarters.

"The IDF has a system of coordinating trips that allows all hikers to be kept safe while in an area that requires security preparedness", the military said in a statement.

According to the Prisoners Society, the Israeli army also arrested six Palestinians from occupied East Jerusalem.

The Israeli army frequently carries out wide-ranging arrest campaigns in the West Bank on the pretext of searching for "wanted" Palestinians.

One of the Israeli escorts suffered a light head wound in the incident after he was hit with a rock.
