Israeli police on Tuesday arrested 15 people for allegedly planning to shoot a Palestinian teenager on a bus, Israeli media reported.

Police said the 15 were members of a group that planned to attack a bus stop in the southern city of Beit Shemesh, where the Palestinian boy was riding.

Police spokesman Micky Rosenfeld said the arrest was the result of the “massive efforts” by the security services.

“The 15 were planning to attack the bus stop, and they are being held for interrogation,” he said.

“We are also working with the media to try to find the other members of the group and bring them to justice.”

The 15 people arrested on Tuesday were among more than a dozen who were arrested in the past year in the West Bank, where Palestinians are regularly arrested and sometimes killed.

Israel, which is occupied by Israel, has faced widespread international criticism for its handling of the wave of violence and has imposed harsh curfews in some parts of the occupied West Bank.

More:Police said one of the men arrested was a member of the Popular Front for the Liberation of Palestine, a group often blamed for violence in Israel and Palestine.

The Palestinian death toll has risen to over 1,000, mostly in attacks carried out by Palestinians, Israeli police said.

Israel’s state-run Israeli Radio said on Tuesday the 15 arrested had been charged with attempting to use “terror weapons” against Israelis and Israeli settlers.

“There are no arrests in the area.

We do not know whether these 15 people were part of a terrorist group or whether they were merely passing through, or whether there was an attempt to commit a crime,” said Yair Golan, a spokesman for the military police.

Israel said on Monday that it would increase security at its West Bank settlements, but said it was not targeting the settlers or Palestinians who live there.
