Heathrow Airport

The plan includes diverting rivers, moving roads and rerouting the M25 through a tunnel under the new runway.

Heathrow's expansion has faced fierce opposition, but the airport says it has engaged with local communities and other stakeholders.

The proposals are now open to public consultation until 13 September.

The masterplan is illustrated in a visualisation from the architects, showing the M25 running in a tunnel underneath the new runway.

Pilots spotted a gadget with multiple arms and up to eight rotors pass by the right hand side of the plane as it was preparing to land.

Both pilots exclaimed: "Was that a drone? At 10,000 feet!", air safety experts UK Airprox Board (UKAB) said.

The drone was estimated to be about 98ft (30m) away from the plane and "safety was not assured", UKAB added.

Large drones are not permitted to fly above 400ft (121m) or within proximity of airports or airfields.

It happened on 11 November 2016, so quickly the Airbus A320 pilots said they had "no time to react".

Police said the warrant for Emmanuel Karenzi Karake, head of Rwanda's intelligence and security service, was made on behalf of authorities in Spain.

Karake, a close ally of Rwandan President Paul Kagame, was one of 40 members of the Rwandan military indicted in 2008 on charges of terrorism and genocide by Spanish national Court Judge Fernando Andreu.
