UK increases threat level to highest

The British government raised the threat level in the country from "severe" to "critical," the highest possible, following an explosion on a London underground station.

Prime Minister Theresa May made the announcement on Friday after a briefing at the Joint Terrorism Analysis Centre on the blast that left dozens injured earlier in the day. The "critical" level of threat means that an attack is expected imminently.

"The public will see more armed police on the transport network and on our streets providing extra protection," May said. "This is a proportionate and sensible step which will provide extra reassurance and protection while the investigation progresses," she added.

Earlier the British police said that the explosion is being treated as a "terrorist incident". The Islamic State of Iraq and Levant (ISIL, also known as ISIS), which has said it was behind several attacks on Western cities in recent years, claimed responsibility through its news agency, Amaq.
