Islamic State Of Iraq and Syria, colloquially known as ISIS, has made it known that the Paris Attacks they stage last week is only the beginning.
They will come back and when they do, they will not just fire guns and bombs.
Intelligence reports speculate the Muslim extremists are now working on chemical weapons in preparation for new attacks they promised to make.
"Islamic State is aggressively pursuing development of chemical weapons, intelligence officials said. The terror group has reportedly set up a branch dedicated to research and experiment with the help of scientists from Iraq, Syria and elsewhere in the region, Iraq and US," Mirror UK reported.
ISIS' Paris attacks saw at least 136 people killed while 352 others were injured. Use of chemical weapons won't shed same amount of blood but they more lethal.
Proof to that is the Ghouta chemical attack in Syria in 2013. US Reports claim the attack, believed to be carried out by forces of Syrian President Bashar al-Assad or the rebels, depending on the source, killed at 1700 people, most of them were innocent.
American authorities do not think ISIS are capable of creating chemical weapons or any chemical that are suitable for a terrorist attack. However, France prime minister Manuel Valls is not resting on being confident.
"Terrorism hit France, not because of what it is doing in Iraq and Syria ... but for what it is," he said in a speech. "We know that there could also be a risk of chemical or biological weapons."
In August of this year, there were reports that the Muslim extremists indeed used chemical weapons when they attacked Kurds in Northern Iraq.
"We have indications that there was an attack with chemical weapons," a ministry spokesman from Iraw said as reported by The Guardian.
"Last Tuesday afternoon, peshmerga forces in the Makhmur area 30 miles (50km) west of the city of Irbil were attacked with Katyusha rockets filled with chlorine."
