Israeli Prime Minister Benjamin Netanyahu has decided to order a full military occupation of the Gaza Strip to force Hamas to free the hostages, according to local reports.

JERUSALEM (AP) — Israel said Friday it will intensify its 22-month war with Hamas by taking over Gaza City, drawing a dismissal from the militant group and renewed international calls to end the conflict, while stirring fears for Palestinian civilians and Israeli hostages still held in Gaza.

It may also reflect the reservations of Israel’s military chief of staff, Lt. Gen. Eyal Zamir, who reportedly warned that expanding operations would endanger the remaining 20 or so living hostages held by Hamas and further strain Israel’s army after nearly two years of regional wars.
