POLICE say the Glengalliagh Road in Derry is closed this afternoon.
It comes as police carry out follow-up enquiries in relation to the security alert yesterday in the area.
Diversions are in place and motorists are advised to avoid the area and seek alternative main routes for their journey.
On Wednesday police said nothing untoward was found after extensive searches.
The searches came after police received a report the previous evening that two viable devices had been left in the area.
