Israel cuts off aid to Gaza

Israel has blocked the entry of humanitarian aid into Gaza, citing Hamas' rejection of a new proposal to extend the ceasefire. Hamas has expressed reservations about the plan because it does not include a commitment from Israel to end the war or fully withdraw its troops. Humanitarian groups warn that cutting off aid now could sabotage the progress made in Gaza during the 44 days of ceasefire. The World's Shirin Jaafari reports.
