BBC analysis// Six months on, how close is Israel to eliminating Hamas?
It has been nearly six months since Hamas fighters broke through from Gaza into Israel on 7 October, killing about 1,200 people and taking hundreds hostage, BBC reports.
In response, Israel vowed to "crush and destroy Hamas" so that it no longer posed any threat, and to bring all the hostages home.
In the brutal war that has followed, at least 33,000 Palestinians have been killed, according to the Hamas-run health ministry, and large parts of Gaza have been destroyed.
Israel says it has killed thousands of Hamas fighters and destroyed much of the vast network of tunnels beneath Gaza, which Hamas has used to carry out attacks.
BBC Verify has combed through public statements and social media posts by the Israel Defense Forces (IDF) and assessed the evidence behind Israel's stated aims.
How many Hamas leaders have been killed?
Before 7 October, Hamas was thought to have about 30,000 fighters in Gaza, according to reports quoting IDF commanders.
Many of Hamas's senior political figures such as Ismail Haniyeh, widely considered to be the group's overall leader, live abroad. But many of its military leadership structure are thought to be inside Gaza.
In a recent statement, the IDF said it had killed about 13,000 Hamas fighters since the start of the war, although it did not say how it calculated that figure.
Israel also publishes the names of individual Hamas leaders it says have been killed.
A total of 113 people have been named in this way since October, the overwhelming majority of whom were reported killed in the first three months of the war. By comparison, the Israeli army did not report any senior Hamas leaders killed in Gaza this year until March.
How many hostages remain in Gaza? According to Israeli official figures, 253 people were taken hostage on 7 October. Of these:
109 have been released as part of prisoner exchanges or in separate deals
3 have been rescued directly by the Israeli army in military operations The bodies of 12 hostages have been recovered, including three that the IDF admitted to killing in one of their operations The youngest confirmed living hostage is 18 and the oldest aged 85.
Of the remaining 129 hostages, Israel says at least 34 are dead.
Hamas says the number of dead hostages is higher - the result of IDF air strikes. But it is not possible to verify these allegations.
How much of the Hamas tunnel network has been destroyed?
As part of its pledge to eliminate Hamas, Israel promised to destroy the group's extensive tunnel network beneath Gaza, which it uses to move goods and people.
"Think of the Gaza Strip as one layer for civilians and then another layer for Hamas. We are trying to get to that second layer that Hamas has built," IDF spokesperson Jonathan Conricus said in October.
Hamas has previously said that its tunnel network stretches for 500km (311 miles), although there is no way to independently verify this.
Israel's offensive has come at a high price
Israel's war aims have come at an immense cost to Palestinians in Gaza. More than 33,000 people have been killed, according to the Hamas-run health ministry.
The ministry's latest demographic breakdown from 5 April indicates more than 70% of those killed were women and children.
