Middle East latest: Palestinian officials say 22 killed in Israeli airstrikes

The Israeli military on Saturday renewed its orders for Palestinians in the northern Gaza Strip to leave their homes and shelters as troops continue a weeklong offensive against militants.

Most of the fighting has centered in and around Jabaliya, which has been pounded by Israeli war jets and artillery. Residents said they have been trapped inside their homes and shelters.

Israel also has been escalating its campaign against Hezbollah with waves of heavy airstrikes across Lebanon and a ground invasion at the border after a year of exchanges of fire. Israel is now at war with Hamas in Gaza and Hamas' ally Hezbollah in Lebanon.

Israel’s offensive in Gaza has killed over 42,000 Palestinians, according to local health authorities, who do not say how many were fighters but say women and children make up more than half of the fatalities. The war has destroyed large areas of Gaza and displaced about 90% of its population of 2.3 million people, often multiple times.
