Besides the killed and injured, a large number of people are missing, feared to be under the rubble, according to al-Mughayyir.
In recent days, Israel has stepped up the war, and hundreds of people have been killed and injured in the Gaza Strip.
The Gaza war broke out after the terrorist-stamped Hamas, which rules in Gaza, launched a comprehensive attack on Israel in 2023. Since then, over 53,000 Palestinians have been killed.
On Sunday, Israel launched a new "comprehensive" offensive in Gaza.
