Increased security measures will be put in place around Hampden for the Scotland v England World Cup qualifier this weekend.

Supporters have been warned to expect delays in entering the national stadium in the south side of Glasgow on Saturday, with people and bag searches taking place.

British Transport Police also confirmed they are providing extra officers for the Auld Enemy clash in a move to "reassure the travelling public but also to deter, disrupt and detect criminality".

The Scottish FA said fans will be searched at the outer cordons on Aikenhead Road, Prospecthill Road, Mount Annan Drive, Somerville Drive and Letherby Drive, with additional bag searches at the turnstiles.

A spokesman said: "The Scottish FA is in constant dialogue with colleagues from Police Scotland, the (English) FA and other key partners to ensure all appropriate safety and security measures are in place for Saturday's match.

"The safety of fans is of paramount importance to the Scottish FA and a range of measures will be implemented as part of an enhanced security operation.

"These increased security measures at Hampden Park will include bag and people searches, and may result in delays in entering the stadium."

Gates at the stadium will open at 3pm, half an hour earlier than originally planned, the Scottish FA said.

The sold-out Russia 2018 qualifier kicks off at 5pm and comes after England won the Group F clash at Wembley 3-0 last November.

The Scottish FA said it will make a request to UEFA to observe a minute's silence prior to kick-off to pay tribute to the victims of the recent terror attacks in Manchester and London.

British Transport Police chief superintendent John McBride said: "We want spectators to have a fun and enjoyable journey towards this match and will be on hand if they need assistance.

"Likewise, we will also be taking a zero-tolerance approach towards any individuals or groups who exhibit antisocial or criminal behaviour.

"There is no place for hooligan or intimidating behaviour and we will be taking firm action against those who are out to cause trouble."

The ScotRail Alliance joined the police in issuing travel advice to supporters ahead of the match.

Extra carriages will be added to services between Edinburgh and Glasgow via Falkirk High, as well as on key services between Glasgow, Aberdeen, Kilmarnock, East Kilbride, Alloa and Stirling.

Jacqueline Taggart, ScotRail Alliance's customer experience director, said: "We want everyone to have great time at the match but, more importantly, to stay safe.

"With this in mind, police and extra staff will be on hand to assist at key locations across our network. Please help them to help you by following their instructions.

"We'll be doing all we can to get fans to and from the match. You can play your part by planning your journey now - remember not to leave it to the last train of the night to get home, as all trains are going to be very busy.

"To help reduce your need to queue, please buy your tickets through to Mount Florida or King's Park in advance - not on the day."
