At least 29 people were injured when a makeshift explosive device blew up in the London stain system during Friday morning's rush hour. No life-threatening injuries have been reported and eight of those injured have been treated and sent home.

British Prime Minister Theresa May told the nation the danger may not be over.

"The Joint Terrorism Analysis Center that's the independent organization which is responsible for setting the threat level on the basis of available intelligence has now decided to raise the national threat level from severe to critical. This means their assessment is that a further attack may be imminent."

The Islamic State group is claiming that the explosion was carried out by an affiliate unit.

The U.N. Security Council is condemning North Korea's highly provocative ballistic missile test that flew over Japan.

The statement welcomed efforts by members of the Security Council and other countries to promote a peaceful and comprehensive solution to the North Korea nuclear issue through dialogue.

After more than a decade of progress, the U.N. [warms] warns global hunger is again on the rise. Joe DeCapua has the story.

The report says the increase in hungry people is mostly due to conflict and climate-related shocks, such as droughts, floods and storms.

For the first time, five U.N. agencies have co-published the annual report.

José Graziano da Silva is FAO director-general. "We have now 850 million people suffering from hunger in 2016. Let me highlight that we are reporting one year ago. (I) hope this year 17 the numbers will be better."

He says the prevalence of undernourished people has also increased.

As the number of Rohingya refugees fleeing violence in Myanmar to Bangladesh reaches nearly 400,000, aid groups are escalating their response to an increasingly urgent humanitarian crisis.

Azmat Ulla with the International Federation of Red Cross and Red Crescent Societies: "Some of the needs are, you know, emergency shelter, house, medical, water, sanitation, hygiene, dignity kits, food and off course, the restoration of dignity because a lot of the ??? have had a very difficult time."

Rohingya Muslims have been fleeing what they say is long-term persecution in Myanmar for decades. But the speed combined with the scale of this latest crisis is unprecedented. This exodus started after insurgents attacked police posts on August 25, killing at least 12 members of the security forces and sparking a brutal crackdown.

Cuban President Raul Castro sent for the top U.S. envoy of the country to address grave concerns about a number of American diplomats harmed in Havana. There was talk of futuristic "sonic attacks" and the subtle threat of repercussions by the United States.

Castro told the U.S. diplomat, Jeffrey DeLaurentis, that he was equally baffled and concerned. Castro also denied any responsibility.

Five Republican senators are urging Secretary of State Rex Tillerson to close the embassy if Cuba does not take swift action to ensure the safety of American personnel.
