Israeli strikes kill dozens in Gaza, health officials prepare polio campaign

WHO officials say at least 90% of the children need to be vaccinated twice with four weeks between doses for the campaign to succeed, but it faces huge challenges in Gaza, which has been largely destroyed by nearly 11 months of war.

Israeli strikes on Saturday killed at least 48 people in the Gaza Strip, Palestinian health authorities said, as clashes took place in central and southern areas of the enclave ahead of the planned start of a polio vaccination campaign.
