Reem Asaad Awad, 33, was killed in the attack on the Al-Rimal neighbourhood of Gaza City, the Turkish state news agency Anadolu reported, quoting a source at Al Shifa hospital. The strike caused extensive destruction to the targeted apartment and nearby buildings. Awad's daughter was rescued from a large fire that broke out after the attack.
Al Jazeera's Ibrahim al-Khalili, reporting from Gaza City, said the strike happened at 4am (01:00 GMT). Israel says it is investigating the strike and claims it targeted a member of Hamas, without providing evidence.
According to Al Jazeera, Israel has killed 1,501 Palestinians in Gaza since it agreed a ceasefire with Hamas last October. The truce was part of a wider United States-backed proposal to end the war. Talks aimed at advancing to the second phase of the US plan, which includes the withdrawal of Israeli forces and the disarmament of Hamas, have stalled.
The agreement allows for 600 trucks of humanitarian aid to enter Gaza each day, but Israeli authorities have continued to impose severe restrictions on supplies entering the enclave, and reconstruction of the war-shattered territory has not begun.
