Pollution levels in the French capital are once again a cause for concern.

Speed limits are being enforced on the ring road around Paris in a bid to increase the purity of the air.

In March, a city-wide car ban was imposed after pollution rose to dangerous levels.

Officials say local pollution and particles from a recent volcanic eruption in Iceland are once again posing a health risk to residents.

They hope there will be some respite over the weekend.
