"There is no other choice, taking into account that the Libyan people must agree that we act to restore security and stability," Sisi said in an interview with French radio Europe 1 aired on Tuesday, Press TV reported.
Sisi’s remarks come after Egypt launched joint airstrikes against the ISIL Takfiri militants’ strongholds in Libya, during which 64 ISIL militants were killed.
According to Egypt's military, the raids were carried out early on Monday against ISIL camps, training sites and weapons storage areas.
The airstrikes followed the release of a video on Sunday showing the beheading of 21 Egyptian Christians by the terrorist group.
The video showed the handcuffed hostages dressed in orange jumpsuits, similar to previous ISIL victims, kneeling down along the seaside in the Libyan capital of Tripoli.
Speaking on national television following the release of the video, Sisi said that Egypt reserves right to respond in a "suitable way" to the killings.
"Egypt reserves the right to respond in a suitable way and time to punish these murderers," Sisi said in a televised speech.
In a statement issued on Monday, the UN Security Council denounced the execution of the Egyptians, saying the Takfiri group lacks respect for any human values.
The Sunday video comes less than two weeks after ISIL militants released another video showing the immolation of a Jordanian pilot held captive by the terrorist group after his plane went down in Syria last December.
