Russia-Ukraine: No sign of de-escalation yet, Nato chief says - BBC News
But signals from Moscow give some cause for optimism, the head of the military alliance says.
If the shops are anything to go by, it's business as usual in the port city of Mariupol in eastern Ukraine, even though the Russian border is only 50km (31 miles) away. We found customers ambling through the well-stocked aisles of one local supermarket. There was no panic buying and no shortages.

Tatiana, aged 74 - who was carefully perusing the sausage selection - was adamant that fellow Slavs would not attack Ukraine. "The invasion is just in our heads," she told me. "Nobody is going to invade. Nobody will beat their brothers."

The tension may now be easing somewhat, but eastern Ukraine has already been a battleground for the past eight years.

Kremlin backed separatists are dug in about 15km for Mariupol. War is already part of the landscape. Some here say - quietly - that they are now afraid of a much bigger conflict, but there's no hint of an exodus.

Close to the border we saw no sign of trouble on the horizon. The only thing coming down the road from the Russian border were tractors, not tanks. But Moscow's designs on Ukraine are a long-term project.
