The clock is ticking for hundreds of migrants in the northern French port city of Calais waiting for a judge to decide whether to postpone an eviction order.

The Lille administrative court ruling on the question says that the decision could come on Thursday — two days after the deadline expired for the state-ordered mass evictions.

A group of humanitarian associations had asked that the state expulsion order for a large swath of the camp be postponed.

Authorities say the order concerns 800 to 1,000 migrants, but humanitarian groups put the count at more than 3,000.

Most of the migrants in the camp want to sneak to Britain by ferry or the Eurotunnel rail service.

Belgium, fearful of a flood of evicted migrants, announced a restoration of border controls Tuesday.
