Delta Air Lines has extended the suspension of its flights between cities in the US and Israel by another month, through October 31, citing “the evolving security environment” as the onslaught on Gaza grinds on, Al Jazeera reports.

The announcement came after American Airlines also extended the suspension of its flights between the US and Israel’s Tel Aviv through March 29 of next year.

Both airlines said customers with tickets on flights that will now be cancelled can rebook, generally at no extra charge, or cancel their trip and get a refund.
