Israel says it has targeted the homes of Hamas commanders as deadly fighting with Palestinian militants in the Gaza Strip enters a 10th day.
Israel said it had tried to kill Hamas military chief Mohammed Deif “several times”. Overnight, two militants died in a strike on an apartment.
Fresh barrages of rockets were also fired into Israel and sirens continued to sound on Wednesday morning.
Ceasefire moves continue behind the scenes but have made little headway.
The BBC’s Yolande Knell in Jerusalem says reports began circulating that a truce – brokered by Egypt – could come into force within days. However, these were quickly denied.
Israeli PM Benjamin Netanyahu said on Wednesday: “We’re not standing with a stopwatch. We are taking care of the operation’s objectives.”
A Hamas leader said that efforts by mediators were “serious and continuous” but that Palestinian demands had to be met.
