On Sunday, Israel once again cut off much-needed food, medicine and fuel into Gaza. Prime Minister Benjamin Netanyahu's government has been clear - the move is meant to pressure Hamas - into accepting a new set of ceasefire terms, in Israel's favour. And against what was agreed by both sides in January's ceasefire deal. But despite Israel's clear intent to use starvation as leverage, the global response has largely been muted. While Arab countries have condemned the blockade - the US and Europe do not appear willing to hold Israel to the terms of the original agreement. So, can Israel ever be held to account? And if so, how?
