From Iran to Gaza, Eid al-Adha celebrations were muted as war dragged on and shortages of food and fuel roiled the region.
Izz al-Din al-Haddad took over the group’s military wing in Gaza last year. Hamas officials confirmed Mr. al-Haddad’s death in an Israeli attack.
The Palestinian children were born prematurely in the early days of the war and moved from a besieged hospital to Egypt. They have now returned home to the enclave, which lies in ruins.
The new war has led to panic buying and a surge in food prices for Gazans as they try to recover from Israel’s two-year offensive against Hamas.
Millions of Gazans have remained without proper housing since the war, according to the United Nations.
Haitham Salem spent 11 months held by Israel without charge and said he endured beatings and abuse. He was released as part of the cease-fire deal, longing to return to his family.
Since the cease-fire took effect, Israel says it has targeted only militants. But death can come for Gazans while on a family outing or sleeping in a tent.
Hamas said the attack on Saturday was a breach of the truce. The militant group did not comment on Israel’s claim to have killed one of its members.
Israel’s military said it had launched attacks across Gaza after Palestinian militants shot at its troops. The six-week-old cease-fire has been pierced periodically by bursts of violence.
There are many questions about whether a plan to rebuild Israeli-held parts of the enclave is feasible or doomed from the outset.
