Netanyahu says Israel will block Palestinian state

An immunization campaign has begun across Gaza with the goal of reaching 44,000 children in three rounds, according to the United Nations Children's Fund.

The campaign -- run by UNICEF, the World Health Organization, the United Nations Relief and Works Agency for Palestine Refugees in the Near East and the Gaza Ministry of Health -- began on Sunday and will go through Nov. 18.

“It is estimated that 1 in 5 children under three years of age are either zero-dose or have missed vaccinations because of the conflict, putting them at risk of vaccine-preventable disease outbreaks,” UNICEF said in a statement.

“The catch-up campaign aims to provide these children with routine childhood vaccines that protect against measles, mumps, and rubella, diphtheria, tetanus, pertussis, hepatitis B, tuberculosis, polio, rotavirus and pneumonia,” UNICEF said.

Hezbollah will not disarm, despite pressure from Israel, including missile strikes on southern Lebanon, Hezbollah leader Naim Qassem said in an address Tuesday.

Strikes from the Israel Defense Forces on southern Lebanon over the past couple of weeks have been increasing in intensity.

Hezbollah is defending itself and the continuation of the aggression cannot last, Qassem said.

"Pressure will not change our stance, and we will defend our land, our people, and our dignity, and we will not leave the future of our generations to the arrogant and the agents," Qassem said.

Tom Fletcher, the United Nations' under-secretary-general for humanitarian affairs and emergency relief coordinator, said in a Monday statement that the UN and its partners "have fed more than a million people" in Gaza since the signing of a ceasefire there last month.

"Nutrition sites have been reopened and hospitals are treating more patients," Fletcher said. "Roads have been cleared. Vital immunizations are being resumed. Water lines repaired. Winter clothes and blankets are being distributed and mental health and psycho-social services delivered."

But Fletcher said that "many obstacles remain" that are preventing the adequate flow of aid into the devastated Palestinian territory.

"We're working to overcome red tape, enable essential humanitarian partners, open more crossings and routes and navigate continued insecurity," Fletcher said.

"With these constraints eased, we can do much more to save many more lives," he added.

The war "has not ended," Israeli Prime Minister Benjamin Netanyahu said on Monday in an address to the Knesset, Israel’s parliament.

"Those who seek to do us harm are re-arming," he said. "They did not give up their aim of destroying us."

Netanyahu said Hamas "will be disarmed" and "Gaza will be demilitarized."

"It will either happen the easy way, or it will happen the hard way," he continued. "But it will happen."
