Wuhan "welcomed the light of day": Eager to go to the stores

Long life in isolation meant delivering goods.
Many settlements in the city are still separated by two-meter-high plastic walls that were erected at the beginning of the crisis with the aim of social distance and isolation of communities. For this reason, the citizens of Wuhan were completely reliant on online delivery.

Queues of Over 10 km at Both Danube Bridges

There is heavy truck traffic at the exit of the Bulgarian - Romanian border. All ferry points are not operating due to the ice flow, announced the Interior Ministry.

This is why there are long queues of vehicles waiting to enter Romanian territory. The queue at Danube Bridge - Vidin is about 14 km, while the queue at Danube Bridge - Ruse is about 13 km.
