An early summer heat wave across Europe is breaking monthly - and in some cities - all-time records, as the continent oven-bakes under dangerous temperatures soaring above 100 Fahrenheit, driven by hot winds from the Sahara.

Police in London were searching for the assailant who detonated a homemade bomb Friday that sent a scorching blast of flame and smoke through a London subway car, injuring at least 29 rush-hour commuters and sending panicked crowds scrambling for safety in what police called a terrorist incident.

Police on Monday released the names of two of the three men who carried out the high-profile attack in the heart of London last week - but one of them was already known for his extremist views among his neighbors and had been reported to authorities years ago.
