Even known Islamic radical groups have condemned the Islamic State (ISIS) for the horrific coordinated terror attacks in Paris on Friday that left at least 129 people dead and more than 300 others wounded.

However, the Palestinian Authority (PA) stood out for saying that the bombings and shootings claimed by the ISIS should be blamed on Israel.

The leaders of Hamas, Hezbollah and the Islamic Jihad have issued official statements condemning the string of terrorist attacks.

The PA, on the other hand, believes that Israel's spy agency, the Mossad, was responsible for the bombings, according to a statement posted on its official newspaper, WND reported.

Ironically, the PA is the organisation deemed by the Western world to be worthy of leading a new Palestinian state in Judea, Samaria and parts of Jerusalem, historically Jewish lands which the fledgling Palestinian government wanted to be ethnically cleansed of all Jews.

The PA claimed that "Israel will benefit" from the Paris attacks, WND said.

Palestinian National Council member Bassam Abu Sharif also believes that Israel planned the attacks in Paris. He went on to criticise U.S. and Western leaders for not taking a stand against Israel and the "Zionists," and implied that the West had a hand in the attacks since it has "used terror organisations before" to carry out Israel's and their own "schemes" in the Middle East, the report said.

In his statement, Hezbollah leader Sheikh Hassan Nasrallah described the Paris attacks as "barbaric.''

"Our people in this region know very well this terrorism the 'Islamic State' has carried out in the French capital. The 'Islamic State' will not last long,'' he said.

He further stressed that the recent attacks in a Hezbollah stronghold in Beirut's southern suburbs, in which 43 people were killed in a double suicide attack on Thursday, will only increase Hezbollah's determination to fight the jihadist movement in Syria. Hezbollah is backing Syrian President Bashar al-Assad in the country's five-year civil war.

Hamas, considered a terrorist organisation by the European Union and the United States, also condemned the ISIS terror attacks, adding that "we pay our deep condolences to the families of the victims and we wish France safety and security."

Other Muslims around the world also expressed outrage and shock at the carnage in Paris.
