Ongoing flareup in tensions
Israeli state radio says nearly 600 Palestinian rockets and mortars have been fired at Israel in the last 48 hours.
On Sunday, rockets fired from Gaza Strip even reached Jerusalem.
Now, the Israeli military is warning this latest operation – dubbed ‘Breaking Dawn’ – could last for a week.
The Israeli Defence Force said its attacks targeted sites linked to PIJ, including the high-rise Palestine Tower in Gaza City.
The latest violence is the most serious flare-up in just over a year.
