A Sinai-based Al Qaeda-linked militant group says that four of its fighters were killed in an Israeli air strike inside Egyptian territory over the weekend.
The Egyptian military has for weeks been conducting extensive operations against terror groups using Sinai as a base of operations. But the group Ansar Jerusalem said Friday's attack on one of its strongholds was different because it was carried out by an unmanned Israeli drone.
Israeli Defense Minister Moshe Ya'alon failed to explicitly deny the claim, but did say that "Israel respects the sovereignty of Egypt" and that the Jewish state would "not allow rumors and speculations...to harm the peace treaty between our two countries."
Other Israeli officials declined to comment on the reports.
Over the weekend, Egyptian forces killed dozens of militants in Sinai, and destroyed a large number of smuggling tunnels running under the border into Hamas-controlled Gaza.
Egyptian officials said that Israel had not violated Egypt's airspace, and denied that the two countries were coordinated attacks on Sinai-based terrorists.
