North Korea

North Korea said might test a hydrogen bomb over the Pacific Ocean after U.S. President Donald Trump vowed to destroy the reclusive country, with leader Kim Jong Un promising to make a “mentally deranged” Trump pay dearly for his threats. South Korea said it was the first direct statement of its kind by a North Korean leader.

Detonating a nuclear-tipped missile over the Pacific Ocean would be a logical final step by North Korea to prove the success of its weapons program but would be extremely provocative and carry huge risks, arms control experts said.

Iran

Iran will strengthen its missile capabilities and will not seek any country’s permission, President Hassan Rouhani said in a snub to demands from Trump. Rouhani was speaking at a military parade where an Iranian news agency said one of the weapons on display was a new ballistic missile with range of 2,000 km (1,200 miles), capable of carrying several warheads.

Cyber

The U.S. Department of Homeland Security detected five “critical” cyber security weaknesses on the Securities and Exchange Commission’s computers as of January 23, 2017, according to a confidential weekly report reviewed by Reuters. The report’s findings raise fresh questions about a 2016 cyber breach into the U.S. market regulator’s corporate filing system known as “EDGAR.” SEC Chairman Jay Clayton disclosed that the agency learned in August 2017 that hackers may have exploited the 2016 incident for illegal insider-trading.

London’s transport regulator stripped Uber of its license to operate from the end of the month, affecting over 40,000 drivers in a huge blow to the taxi app. “Uber’s approach and conduct demonstrate a lack of corporate responsibility in relation to a number of issues which have potential public safety and security implications,” Transport for London (TfL) said.

Jitters over a fresh exchange of barbs between North Korea and the United States eased in Europe as strong economic data supported European stocks, and investors’ focus turned to a planned speech by Britain’s prime minister on Brexit.

From her early days as Federal Reserve chair, Janet Yellen has been the target of criticism from Republicans worried that the central bank’s massive bond-buying programs and near-zero interest rates engineered by her predecessor would be the ruin of the country. With little more than four months left in her term and questions swirling over whether the White House will ask her to stay on for another four years, Yellen has turned that story around.

Meet the Nujaba militia: based in Iraq, backed by Iran, pushing across Syria.
