Supporters of the Islamic State (Isis) have reportedly hailed Donald Trump's historic victory in the 2016 US presidential race, saying it marks the beginning of the fall of the country.

While several political leaders from across the globe joined in welcoming the Republican to the White House, the jihadists too cheered for the new president-elect.

They took to social media at the prospect of a Trump presidency, with one user writing: "9/11 was the beginning of the renaissance of the Muslim nation. 11/9 will be the beginning of the fall of the Satan (America) of this age". A screenshot of the message was shared by Rukmini Callimachi, a New York Times journalist focusing on IS (Daesh) and al-Qaeda.

"The real winner in the American elections is the policy of Sheikh Usama Bin Laadin," the user added.

Pointing out how Trump had won despite being "openly racist" towards Muslims and other minority groups, a user named Khorasani said the majority of the Americans had similar views and "mindset".

"This shows the true colours of the Americans and how corrupt they all are with no moral values whatsoever," Khorasani said.

"Trump's victory is a hard slap to those promoting the efficiency of democratic systems," The Independent cited Hamza al-Karibi, a spokesperson for the al-Qaeda affiliated Syrian jihadist group Jabhat Fatah al-Sham, as saying to his Twitter followers. "Starting today, we won't need media releases clarifying the West's machinations. All we need to do is retweet what Trump says".

Pro-al-Qaeda supporters too cheered Trump's victory as signalling a decline of the US. The al-Maqalaat Twitter account said Trump would "make the US Enemy No. 1 again" in the Middle East.

"Trump will serve as the perfect straw man for the next four years, like Bush did before him," Washington Post quoted it as saying.

Another al-Qaeda-linked ideologue, Abu Muhammad al-Maqdisi, who has over 56,000 followers on Twitter, declared that Trump's term "may be the beginning of America's disintegration and the era of its breakup".

"Rejoice with support from Allah, and find glad tidings in the imminent demise of America at the hands of Trump," said the IS-affiliated al-Minbar Jihadi Media network. It was one of several jihadi forums to post its comments soon after the results of the US elections were declared.
