As Israel withdraws some of its troops from Gaza during a cease-fire there, it has turned attention to another Palestinian territory — in particular a city with a history of militant activity.

Israeli security forces backed by helicopters raided the volatile West Bank city of Jenin on Tuesday, killing at least eight Palestinians in what Prime Minister Benjamin Netanyahu called a "large-scale and significant military operation." Fadi Al-Saadi's brother was killed in the raid. This video contains distressing images.

In the days since a fragile ceasefire took hold in the Gaza Strip, Israel has launched a major military operation in the occupied West Bank and suspected Jewish settlers have rampaged through two Palestinian towns.

Israel says it has killed two armed men, suspected of carrying out a shooting attack that killed three Israelis in the occupied West Bank earlier this month. Qutaiba Shalabi and Mohammed Nazzal were killed after a fierce gun battle with Israeli forces on Wednesday night in Burqin,

At least 10 people have been killed in the raids, and more than 40 wounded, according to the Palestinian Health Ministry. Dozens have been arrested, Palestinian officials told the Wafa news agency.

Gunfire and explosions rocked the Jenin area of the occupied West Bank on Wednesday, an AFP journalist reported, as the Israeli military kept up a large-scale raid for a second day.
