United States President Barack Obama called for stringent global action against the Islamic State, while speaking at the G20 summit in Antalya, Turkey on Monday. “Tragically, Paris is not alone. We have seen outrageous attacks in Beirut, in Ankara and routinely in Iraq,” he said, according to The Guardian. Calling ISIS “the face of evil”, Obama said this was not a regular war where two states were fighting each other, but a special case that needed more nations to band together against the militant group. He also said that the US has even been reaching out to Russia and Iran to end ISIS' reign of terror, and that merely bombing them would not solve the problem.

Obama's words came hours after ISIS purportedly released a new propaganda video threatening an attack on Washington DC. Using news footage from Friday’s terrorist attacks in Paris, the militant group warned of more carnage, though the video's authenticity has not been verified yet. It shows a militant issuing a warning that "any country" participating in airstrikes against IS would be targeted as Paris was.

In response to the attacks in Paris, French military jets targeted Raqqa, the Islamic State’s de-facto capital, launching their most intense airstrikes in Syria, on Sunday.
