Shots were fired at an Israeli bus south of Ramallah on Sunday evening. No injuries were reported.

The bus, traveling near the Israeli settlement of Anatot in the West Bank, northeast of Jerusalem, was lightly damaged by the shooting, NRG reported. IDF forces were searching the area for the perpetrators.

In a separate incident, Border Police foiled a terrorist attack on a West Bank checkpoint Sunday, arresting three Palestinians at the Tapuach junction, south of Nablus and east of the Ariel settlement.

Authorities found seven pipe bombs and several improvised weapons in the suspects’ car, reported Israel Radio. The three men admitted to planning an attack on the checkpoint during questioning.

The number of terror attacks in the West Bank rose from 320 in 2011 to 578 in 2012, while 282 attacks were carried out in Jerusalem, compared to 191 in 2011.

According to a Shin Bet report released Thursday, the increase is due in part to a 68% rise in what the security agency refers to as “popular” terror attacks — mainly attacks involving Molotov cocktails. However, the number of attacks involving firearms and explosives also grew by 42% — 37 compared to 26 in 2011.

Ten Israelis were killed as a result of terror attacks in 2012, compared to 22 killed in 2011. Six of the victims were civilians and four were members of the security forces.
