Mr Obama is due to end his African tour with a visit to Tanzania, where he will pay his respects at a memorial outside the US embassy in the main city, Dar es Salaam, in honour of 11 people killed in a bombing by al-Qaeda in 1998.

He has excluded from his itinerary Kenya, where his father was born, and Nigeria, Africa's biggest oil producer which has been hit by an Islamist insurgency. ISIS counting on anti-Muslim backlash 'to sharpen the divide,' experts warn Experts say the group wants to drive a wedge between Western Muslims and others.

 -- As ISIS claims responsibility for one attack after another, experts warn that understanding the terrorist group’s geopolitical, ideological and religious motivations are crucial to stopping it.

The U.S.-backed military offensive to retake ISIS-held areas of Iraq and Syria, coupled with propaganda during the holy month of Ramadan, could be contributing to the recent increase in attacks in Europe.

Experts also say an ongoing directive from the group's leaders for believers to fight with whatever is available and anti-Muslim backlash in Western societies after such attacks may also play a key role.

"I think you've seen a slight uptick right now because ISIS has put out a message to its followers saying, 'Don't come to Syria, don't come to Iraq, stay at home and create a problem,'" Jeffrey Ringel, a director at the Soufan Group and 21-year veteran of the FBI, told ABC News.

"That message came out about a year ago when it became more difficult for people to go there. ISIS was losing its land mass, they were losing their caliphate, so the leader of ISIS basically encouraged followers to stay home and attack Westerners in their own backyards," Ringel added.

There's no doubting ISIS's shrinking land mass.

By early Tuesday morning, fighters from the Syrian Democratic Forces had retaken nearly 4 square miles outside of the city of Raqqa as part of their latest offensive against ISIS. And Iraqi forces had successfully fought to retake about 190 square miles from ISIS near Mosul, according to a May 5 U.S. Department of Defense news release.

ISIS propaganda during the holy month of Ramadan, when Muslims around the world devote time to fasting, studying the Quran and cleansing their spirit, is also a factor, according to Joby War
