Prague is the Capital of the Czech Republic (🗣️ "Check Republic"), a small country sandwiched between Austria, Poland, Germany and Slovakia in the centre of Europe. I think it is an interesting place to visit. I won't try to name the assailant because fame may have been his motive, we don't know why he did it. He shot his Dad first so I don't think he was following a cult. Most religions promote the respect of your parents.
Iceland is full of volcanoes, I think they even use geothermal heat to fuel their power stations. Britain is close to Iceland, it is about 1000 km from Britain. I think this recent eruption came from a fissure vent.
