Alaa al-Najjar, a Gazan paediatrician, found her family's house on fire after the strikes, her husband, fellow doctor Hamdi al-Najjar, was severely wounded and their only surviving child, an 11-year-old son, is in a critical condition.

In short:

Nine of two doctors’ 10 children were killed in Israeli air strikes that hit Gaza in the past 24 hours, according to the Gazan health ministry.

Israel has stepped up its campaign of strikes on Gaza in recent days, drawing international criticism and calls to allow in more supplies after it partially eased a total blockade on aid.

Warnings of famine by food security experts have led Israel’s allies to press Prime Minister Benjamin Netanyahu’s government to allow more aid to return into Gaza.
