Palestinian Islamist terror group Hamas on Friday dismissed as "propaganda" an Israeli claim that it provided support related to this week's jihadist attacks against Egyptian soldiers in Sinai.
"The occupation's (Israel) statements about Hamas helping IS are stupid accusations... and propaganda that aims to incite against Hamas," spokesman Sami Abu Zuhri told AFP, referring to the Islamic State terrorist group (also known as ISIS), whose fighters carried out the attacks.
"Hamas has made efforts and taken stated measures to secure the border" between the Gaza Strip, which it controls, and Egypt's Sinai Peninsula, he said. "We are intent on (preserving) Egypt's security."
Israeli Major General Yoav Mordechai said in an interview in Arabic with Al-Jazeera television Thursday that Hamas had provided help to "groups supporting IS" for the attacks, claiming also that wounded jihadists had been smuggled into Gaza.
Medical and security officials said at least 70 people, mostly soldiers, were killed in Wednesday's attacks and hours of clashes, along with dozens of jihadists.
There have however been growing tensions between Hamas and Salafist splinter groups in Gaza, including those claiming links to ISIS.
Such tensions have deepened since last summer, when Israel and Hamas fought a deadly 50-day war in and around Gaza.
The extremists have made no secret of their disdain for Hamas over its observance of a tacit ceasefire with Israel and its failure to fully implement Islamic law.
Gaza terrorists who said they support ISIS claimed responsibility for three separate attacks in May, including a rocket attack on a base of Hamas's armed wing.
They also have claimed responsibility for rockets recently fired at southern Israel in defiance of the truce, prompting Israel to retaliate with air strikes.
