Police were today reportedly involved in a car chase after a vehicle containing four 'heavily armed men' stormed through a motorway toll road and headed towards Paris amid fears of further terror attacks.

French police were said to be in pursuit of a Citroën Berlingo after it forced its way through a toll on the A10 in the Ablis area of Yvelines in north-west France at lunchtime today.

The town is approximately 40 miles from the centre of Paris and the incident comes as police remain on high alert following a string of deadly terror attacks across the French capital last night.

Police also confirmed they are currently hunting a black Seat vehicle, registered abroad, which is 'wanted in connection with the attacks'.

France remains on high alert after a string of barbaric terror attacks were carried out across the French capital, leaving at least 129 people dead.

France went into lockdown overnight and French President Francis Hollande closed the borders.

Following the attacks, the French President declared a state of emergency and said: 'To all those who have seen these awful things, I want to say we are going to lead a war which will be pitiless'.

He also ordered that 1,500 soldiers be deployed to Paris after the string of violence and that French borders are closed to prevent suspects' escape.
