German Chancellor Angela Merkel has said that Nato stands by the Founding Act even though Russia has broken it through its actions in Ukraine.
She said that new EU sanctions against Russia, due to be adopted today, could be suspended if a promised ceasefire materialises.
The Founding Act is a 1997 agreement between Nato and Russia agreeing how they are to pursue relations. Among other things, it covers the "permanent stationing of substantial combat forces".
Cab service Uber has been banned in Germany in the latest shot in a fight with the country's taxi drivers.
The ruling comes after Berlin authorities barred Uber from operating in the capital last month because of safety concerns.
The injunction applies pending a full hearing of a suit brought against Uber by a German group that offers a taxi-ordering app.
Their arguments were in line with those of established cab companies which claim Uber's app-based services, which offer limousines and pickups by private drivers, dodge rules that ordinary taxi firms have to abide by.
Black cab drivers in London have protested about California-based Uber, claiming its app contravenes rules that restrict the use of taxi meters. Protests have also taken place in Paris and Madrid.
Russian President Vladimir Putin has reportedly told German Chancellor Angela Merkel that he decided to send a humanitarian aid convoy into Ukraine because he could no longer wait.
According to the Kremlin account of the phone call, President Putin expressed "serious concern" about the military escalation in eastern Ukraine.
Germany's foreign minister has said his government is willing to send arms to Iraq and that it will provide military equipment in the coming days.
Germany's foreign intelligence agency recorded at least one phone conversation held by US Secretary of State John Kerry, a German magazine reported.
Der Spiegel cited unnamed sources as saying Germany security agents had intercepted Kerry's words when he was in the Middle East negotiating between Israelis, Palestinians and Arab states last year.
But the intelligence agency spokeswoman told Reuters Germany was not tapping the phones of allied countries and said the United States was not a target.
Germany's foreign minister has said he would go to the limits of what is "legally and politically possible" in terms of arming Iraqi Kurdish fighters.
He said he would ask what the Iraqi government expects of Europe on an upcoming trip to the country, and then decide how to proceed.
The £60 million settlement in Bernie Ecclestone's bribery trial may seem a lot of money, but it leaves the road clear for one of sport's biggest operators to carry on exerting control over the world of Formula 1.
ITV News Sports Editor Steve Scott reports:
Formula One boss Bernie Ecclestone has to pay $100 million (£60m) as a settlement payment in his bribery trial, a Munich district court said.
A spokesman for the court said the suspicion against the 83-year-old was largely not substantiated.
The bribery trial against Formula One boss Bernie Ecclestone will be discontinued for the moment, a Munich district court said.
The announcement comes after the 83-year-old offered to pay a £60 million settlement to end the trial.
Bernie Ecclestone's defence lawyer has said it is "do-able" for the Formula 1 tycoon to pay out £60m within a week.
A district court in Munich said Mr Ecclestone, 83, had offered to pay the cash to end a trial for bribery.
The state prosecutor told the court that Mr Ecclestone's age and other circumstances meant they would support the offered settlement.
The billionaire could face up to 10 years in jail and have to give up control of his business if he is found guilty.
A spokeswoman for the Munich court pointed out that under German law settling the case with a payout did not amount to an admission of guilt.
"With this type of ending a procedure there is no ruling on guilt or innocence of the defendant," she said.
"He is neither acquitted nor judged, rather this is a special type of ending a procedure which is in theory available to all types of cases."
