What is the Islamic State?
The jihadist group burst on to the international scene in 2014 when it seized large swathes of territory in Syria and Iraq.
It has declared the establishment of a "caliphate" across the two countries - a state governed in accordance with Islamic law, or Sharia.
At its height, the group is thought to have controlled an area of about 210,000 sq km (81,000 sq miles) - roughly the size of the UK, but that area has shrunk.
US forces estimated late last year that IS had been reduced to about 15,000 fighters following the reported death of about 45,000 fighters over two years.
The diminishing group has pursued a tactic of encouraging so-called lone-wolf attacks outside of its territory. The most deadly strike linked to the group killed 130 people in Paris in 2015.

As the advance got under way, the UN commissioner for human rights called on the Iraqi government to investigate videos shared on social media that appeared to show Iraqi troops brutally abusing and executing IS fighters on the streets of east Mosul late last year.
The videos have not been verified at this stage by any government authority or independent group. The Iraqi prime minister's office said it had launched an investigation.
The offensive on the eastern part of the city was launched on 17 October, more than two years after jihadists overran Mosul before seizing control of much of northern and western Iraq.The offensive on the eastern part of the city was launched on 17 October, more than two years after jihadists overran Mosul before seizing control of much of northern and western Iraq.
