Tourists were attacked by gunmen on a motorcycle as they boarded a bus outside their hotel in the Egyptian capital of Cairo.Thursday's attack took place outside the Three Pyramids Hotel which is situated on a road leading to the pyramids, according to security sources who added that there were no casualties. One gunman was arrested at the scene while security forces surrounded the other in another part of Cairo, according to sources. Tourism is a pillar of the Egyptian economy which has been struggling to recover from political turmoil triggered by the 2011 uprising that toppled former president Hosni Mubarak. Egypt declared it would step up security at major tourist attractions last year after several attacks that caused its already struggling tourism industry to slump further. In June, two policemen were shot dead close to the pyramids. President Abdel Fattah al-Sisi, who took power after ousting the country's first democratically elected president Mohamed Morsi in 2013, has declared an all-out war on armed groups, according to Aljazeera.
