UK is working to rescue its citizens as 'scared and desperate' people begin looting food
"Officials said that Israel and Egypt were prepared to let foreigners leave the Strip which is under heavy Israeli bombardment, but Hamas had refused."
I'm not sure what part you meant since the article talks about how they can't flee not because of the bombing but because the border is closed by Egypt
Egypt has refused to open its doors to those fleeing Gaza — in part because it doesn’t want to be seen as aiding Israel’s forced displacement of Palestinians but also because it doesn’t want a massive refugee crisis within its borders.
I thought your claim was that they're not crossing because of the bombing, but in the article you linked they're saying they're still trying to cross and the the reason they're unable to is Egypt.
