A Dashboard camera caught a moment when shells hit a residential area in Ukraine's strategic port of Mariupol on Saturday (January 24).

The video obtained from Mariupol resident Viktor Zubritsky who posted it on Youtube shows a car driving along the street behind another vehicle when shells started exploding ahead. Reuters cannot further verify its content.

Pro-Russian rebels launched an offensive against the strategic port of Mariupol in eastern Ukraine on Saturday, prompting the European Union's foreign policy chief to warn of a further "grave deterioration" in EU-Russian relations.

Mariupol's city administration said the rebels had killed at least 30 people and injured 83 others by firing rockets from long-range GRAD missile systems.
