The U.N. World Health Organization says it's reached an agreement with Israel for limited pauses in fighting in Gaza to allow for polio vaccinations for hundreds of thousands of children. It comes after a baby contracted the first confirmed case in 25 years in the Palestinian territory. The WHO representative in the Palestinian territories said Thursday that vaccination campaign will start Sunday in central Gaza, with a “humanitarian pause” lasting from 6 a.m. until 3 p.m. for three days. The effort will then move to southern Gaza and finally northern Gaza for similar pauses. The agency says the campaign has been coordinated with Israeli authorities.
