The Federal Aviation Administration says it'll give airlines an update by midday Wednesday on its banning of flights between the U.S. and Israel.
The flights were canceled Tuesday after a rocket fired from the Gaza Strip landed near Tel Aviv's Ben-Gurion Airport.
U.S. airlines acted ahead of the FAA Tuesday and indefinitely canceled all future flights to and from Israel.
Meanwhile dozens of Palestinian families trapped by clashes between Hamas militants and Israeli troops are scrambling to flee a southern Gaza Strip neighborhood as Israel reported on Wednesday that two more of its soldiers have died in the conflict.
The Palestinian Red Crescent says it's trying to evacuate about 250 people from near Khan Younis, which has been under Israeli tank shelling and drones strikes Wednesday morning.
As the fighting near Khan Younis rages, the Israeli military says two more soldiers have been killed, raising the military's death toll to 29. That doesn't include one Israeli soldier whose remains have not yet been found.
The circumstances of the latest military casualties were not immediately clear. Two Israeli civilians have also died in the 15-day conflict.
The fighting has killed at least 630 Palestinians.
