A powerful earthquake struck southwestern Japan near Kumamoto City overnight, killing at least nine people according to NHK and injuring several more.  Many older homes that were built in the days before Japan's super-tough earthquake standards came into force were heavily damaged or destroyed.  Officials say 30,000 people sought help in emergency shelters.  More than 70 aftershocks rocked the area, and people are being advised to prepare for more shaking as well as building collapses and landslides.  Japan's national broadcaster NHK's cameras caught it as the tremors hit Kumamoto City, shaking the dust off of Kumamoto castle and severely damaging parts of the stone wall around the site, which is considered an important cultural asset.

The Japanese government says there are no abnormalities at the Sendai and Genkai Nuclear Power Plants, which are located near the epicenter in Kagoshima and Saga prefectures, respectively.  Sendai is the only one of Japan's nukes to go back online after the Fukushima Nuclear Disaster in 2011.  And the Shinkansen bullet train holds on to its incredible safety record; one Shinkansen derailed, but it was not carrying passengers and was on its way to a maintenance yard at the time.

The Nigerian Islamist insurgent group Boko Haram released video that apparently shows some of the Chibok girls, who were among the more than 200 who were taken in a mass abduction from the boarding school in that town two years ago.  Apparently filmed on Christmas Day 2015, it shows the girls pleading with the Nigerian government to co-operate with militants on their release.  The 15 girls in the video said said they were being treated well but wanted to be with their families.  It's the only proof-of-life of the Chibok girls in almost two years.

After weeks of fighting, Iraqi forces have retaken the town of Hit back from Islamic State.  Victory had been seen as key to the government's wider campaign to regain control of Anbar province.  But the thing about terrorists is that they're not always loyal or attached to any particular piece of real estate.  US President Barack Obama warned that Islamic State recruits are increasingly heading to Libya following the setbacks the militant group has suffered in Iraq and Syria.  Mr. Obama says the "worst mistake" of his presidency was failing to plan for the aftermath of the ousting of Libyan leader Moammar Gaddafi in 2011.

Brazil's government has gone to the Supreme Court to try and stop the impeachment process against Dilma Rousseff.  Her opponents claim Dilma manipulated state accounts to make her government's economic performance appear better than it was.  Attorney General Jose Eduardo Cardozo filed the emergency request for an injunction against the drive to remove Dilma from office, saying that no crime had taken place.  If the court refuses the injunction, Brazil's lower house is expected to vote on the matter on Sunday.  If two-thirds approve, impeachment goes to the full senate.

Migrants and refugees would have to learn the German language and takes additional steps to assimilate, under a new bill proposed by Germany's ruling coalition.  The courses in German life, the language, and job training would be subsidized, but migrants could still be told where to live as the country struggles to deal with the influx of more than a million refugees over the past year or so.  "We will have a German law on integration - this is the first time in post-war Germany that this has happened," said Chancellor Angela Merkel.  "It is an important, qualitative step."
