Will British aid workers be able to leave Gaza? How will hospitals cope?
Bunkall says Israel closing the Rafah crossing between Gaza and Egypt today will make things "progressively worse" for aid workers and hospitals in the enclave.
"That crossing in recent weeks was staffed by a mission from the EU, bussed in every day from Egypt to man the crossing and allow Palestinians out if they were approved to leave by Israel," he explains.
"I think it's too early to know how any aid workers in Gaza will get out. Often in the first days of conflict in Gaza, everything remains shut."
On the situation for hospitals in Gaza, Bunkall says most of them have been "pretty much destroyed" thanks to fighting going on for the last 15 months.
"The last two months of the ceasefire have helped get supplies in like food, water, medical supplies, generators, fuel to a point where they can function.
"But everything we're hearing from doctors in Gaza today is that they've been overwhelmed as a result of the strikes."
He adds: "Just to remind you, Israel blocked humanitarian aid from getting into Gaza a week or so ago and then shut off electricity supplies it supplies to a desalination plant in Gaza.
"All of that will make things progressively worse."
