Aid groups and U.N. investigations have accused Israel of aiming to destroy Gaza’s health infrastructure. Israel says it is forced to strike hospitals it says are used by Hamas for military purposes.

Israel has targeted Hamas leader Mohammed Sinwar in a strike on a hospital in southern Gaza on Tuesday evening, according to a senior Israeli official and two sources familiar with the matter.

Israel's attacks in Gaza this week send the signal they are not interested in negotiating a ceasefire, Qatar's prime minister told CNN in an interview on Wednesday.
