Israel has long blamed Hamas for civilian and children deaths, arguing that the militant group uses innocent people as human shields.

Palestinian authorities say 15 people were killed overnight in the Gaza Strip in multiple Israeli attacks. An airstrike early Friday morning in Gaza City hit a family home, killing six people including an unknown number of children, Gaza’s Civil Defense said. Another person was killed in Gaza City when a strike hit a group of people on a street.

Polio vaccination teams successfully reached more than half a million children in Gaza during Round One of an ambitious campaign.

In a bid to counter malnourishment in Gaza, the UN will add nutrients to the second round of the polio vaccination campaign. As per the global health organization, over 3,000 children are undernourished.
