Humanitarian pauses have been agreed to allow a second round of polio vaccinations targeting 590,000 children under the age of 10 to start in the Gaza Strip on October 14, the head of the UN children’s agency Unicef has said, Reuters report.

“Area-specific humanitarian pauses have been agreed. It is critical that these pauses are respected by all parties. Without them, it is impossible to vaccinate the children,” Unicef Executive Director Catherine Russell said in a statement.
