Israeli Prime Minister Benjamin Netanyahu has hit out at his security minister after video footage showed him taunting detained activists from the Global Sumud Flotilla who had been attempting to transport aid to Gaza.

Footage released by Israel's National Security minister Itamar Ben-Gvir earlier this week had shown him berating detainees and waving a large Israeli flag as they were forced to kneel with their hands tied behind their backs.

“Welcome to Israel, we are the landlords,” he says in the video.

In a statement, Netanyahu said Israel had "every right" to stop "provocative flotillas of Hamas terrorist supporters from entering our territorial waters and reaching Gaza."

But he stressed that the manner in which Ben-Gvir had dealt with the activists was "not in line with Israel’s values and norms."
