Hamas Prime Minister Ismail Haniyeh said on Saturday that Palestinians would never forget the "sacrifices" made by Egypt for the Palestinian cause.
"The security, stability and political strength [of Egypt] positively reflect on the whole Arab world, and no one will accept interrupting those elements," Haniyeh told El-Sayed El-Badawi, head of Egyptian opposition liberal Wafd Party in a phone conversation reported by Egypt's state-run news agency MENA.
Media controversy has been growing recently about who killed 16 Egyptian border guards near Rafah in the Sinai Peninsula last year, following recent anonymous leaks that blamed perpetrators from Gaza.
Al-Ahram Al-Arabi, a state-run Egyptian weekly magazine, sparked controversy on Thursday by claiming three Hamas members were responsible for the operation.
The alleged perpetrators were Ayman Nofal, a leading figure in Hamas's military wing, the Qassam Brigades, who escaped from an Egyptian prison during the January 25 Revolution; Mohamed Ibrahim Abu-Shamala, also known as Abu Khalil; and Raed Attar, who lead the team that captured Israeli soldier Gilad Shalit in June 2006.
The magazine claimed security officials had confirmed the information, adding the attack was carried out in response to the Egyptian military's decision to destroy tunnels linking Egypt and Gaza, a lifeline for people in the besieged enclave.
Other Egyptian tabloids, and some newspapers in the Gulf, also circulated reports accusing Hamas members of orchestrating the attack.
