An extraordinary warning call to a Palestinian dentist starts the panicked evacuation of a Gazan neighbourhood.

The call to Mahmoud Shaheen came at dawn.

It was Thursday 19 October at about 06:30, and Israel had been bombing Gaza for 12 days straight.

He’d been in his third-floor, three-bedroom flat in al-Zahra, a middle-class area in the north of the Gaza Strip. Until now, it had been largely untouched by air strikes.

He’d heard a rising clamour outside. People were screaming. “You need to escape,” somebody in the street shouted, “because they will bomb the towers”.
