The World Health Organization is deeply concerned about violence in the Israeli-occupied West Bank and the impact of what it called "starkly rising" attacks on healthcare, its representative in the Palestinian territories said on Tuesday.

Israel launched a major military incursion in the northern West Bank in August, which it called “Operation Summer Camps.” It sent armored vehicles into the cities of Jenin and Tulkarem, severing water and electricity and leading Palestinians to ration food, residents told CNN.

Amid the most intensive Israeli operations in the area in decades, Palestinians fear entrenched displacement and a return to military control in some towns.

Israel’s military sent tanks into the occupied West Bank for the first time in more than two decades as it expanded operations in the territory on Sunday in a move decried by Palestinian authorities as an escalation of aggression.

The UN chief voiced alarm Monday at rising violence by Israeli settlers in the West Bank and calls for annexation after Israel announced expanded military operations in the occupied Palestinian territory.
