The Turkish diplomatic service is to assist citizens who want to leave Gaza, as the Israeli bombardment of the Palestinian territory shows no sign of ending.

A statement posted on Saturday on the Foreign Ministry's website asked Turkish nationals to contact the embassy in Tel Aviv or the consulate in Jerusalem.

There are 120 Turks in Gaza, some working for NGOs and others married to Palestinians.

The announcement comes as Israel's military offensive, Operation Protective Edge, continues and the casualty toll mounts. Attacks have left 121 Palestinians dead and 904 others wounded since Tuesday.
