The extremist Islamist group currently wreaking havoc in Iraq and Syria, which has prompted US airstrikes to prevent a potential genocide, was even too brutal for the mastermind of the September 11 attacks, Osama bin Laden.According to a report in the Daily Mail, among the items found in the Pakistan compound where the former al-Qaida leader was killed by US special forces in 2011, was a 21-page letter warning of the dangers of the Islamic State, formerly known as ISIS.In the letter, Bin Laden reportedly called for al-Qaida to sever all ties with the group due to its extreme brutality.console.log("BODY2.

Making the case for why al-Qaida should distance itself from ISIS, the Daily Mail reported that the letter listed a number of atrocities committed by the group, including the use of chemical weapons, bombing mosques and massacring Catholics in a church in Baghdad.
