Israeli soldiers carried out widespread raids in the occupied West Bank early on Tuesday, leaving six Palestinians dead and up to 20 others injured, according to the Palestinian Health Ministry.

Wadih Al Houh, a militant leader of a new Palestinian fighting alliance known as "The Lions' Den," was among those murdered in the northern West Bank city of Nablus, according to Israeli Prime Minister Yair Lapid.

The Israeli army said it had carried out a vast operation with police and intelligence officers targeting a site “used by the main operatives of the Lion’s Den,” describing it as a “headquarters and a workshop for making weapons” of the militants.

Violence has increased in recent months in the northern West Bank, the Palestinian territory occupied since 1967 by Israel, especially in the areas of Nablus and Jenin.

More than 100 Palestinian fighters and civilians have been killed since the start of the year, the heaviest toll in the West Bank for nearly seven years, according to the United Nations.
