Passengers are being advised to check before travelling by tram on Tuesday morning as services remain affected by the incident on Broad Street.

Network operators say there are still no services running between Cathedral and Woodbourn Road, while there are also no trams going between Malin Bridge and Sheffield Station.

In an update on its website at 18:00 GMT, a Supertram spokesperson said the page would be updated at 09:00 GMT on Wednesday and urged people to check the service's social media accounts for the latest information before travelling.

It has now been 24 hours since emergency services were first called to the Gateway apartment building in Sheffield to deal with an incident that has brought part of the city to a standstill.

Armed police were sent to the block of flats on Broad Street at about 19:00 GMT on Monday after reports of a man with weapons inside an apartment.

That led to dozens of residents being evacuated to the nearby Ponds Forge sports centre.

South Yorkshire Police issued an update earlier saying officers were continuing to negotiate with the man and the force's aim was to "bring the incident to a close safely".

As the evening sets in, several roads around the area remain shut with trams and other public transport also affected.

We've heard more from Gateway apartments resident Oliver King, who is worried about pets still in the building.

"We decided to take our dog out of the property and thank goodness we did, because a lot of people have unfortunately still got their pets inside," the 26-year-old said.

"Close friends of ours have three dogs who are in there, two of them are rescues and they’re going to be quite upset as you can imagine."

He continued: "They’re in a crate - I can only imagine it will be very scary for them and I do hope they get out soon."

We've not seen a huge amount change over the last few hours. We've seen armed police officers on a balcony speaking to someone on the top floor.

We've no idea how long this will last. There has been no suggestion of an end time. We were told during the rush hour this morning that this could be a long drawn-out affair and it has been exactly that.

The updates we've had from the police have been minimal - the last one was more than three hours ago.

It's been a long, slow process but ultimately for the police they don't want to be rushing anything.

As the light starts to fade there's nothing imminently happening. Expect these roads to be closed for some time.

Network operators say there are still no services running between Cathedral and Woodbourn Road, while there are also no trams going between Malin Bridge and Sheffield Station.

Reduced services are currently operating between the following places, according to the network website, external:

- Cathedral and Middlewood

- Meadowhall and Woodbourn Road

- Halfway and Sheffield Station

- Woodbourn Road and Rotherham Parkgate

Where I'm standing on the edge of Duke Street, police remain at the scene almost 24 hours after they first arrived.

At the very top of the Gateway apartments we can see police at the edge of a balcony, seemingly in negotiation with the man inside the building.

Students have been allowed back into the neighbouring block of flats and we've recently seen many young people returning.

Otherwise there is no new information and it is a waiting game here at this eerily quiet Park Square roundabout.

Drone footage from the scene shows the scale of the response from emergency services, with police vehicles, ambulances and fire engines all in attendance.

A large police cordon stretches around the Gateway building, with usually busy roads deserted.

It's about 20 hours now since police were first called to the Gateway apartments in Sheffield in response to concerns about the safety of a man inside the property.

Officers later said he was allegedly in possession of weapons.

The apartments were evacuated as armed police descended, with around 80 people taking refuge overnight at Ponds Forge sports centre

A cordon remains in place at the scene this afternoon, with police still said to be "negotiating" with the man in question.

With the incident still ongoing, it means further disruption to travel in the city during the evening rush hour.

The evacuated residents - many of whom rushed out of their homes without essentials like medication - are hoping to know if and when they will be allowed back into their properties.

It's possible they will have to spend a second night in the sports centre if the stand-off does not conclude soon.

As we head into rush hour, several road closures are still in place in the city centre as emergency services remain at the scene.

Sheffield Parkway between Park Square roundabout and Derek Dooley Way remain closed in both directions while specialist officers continue to negotiate with the man, South Yorkshire Police said.

The force urged people to continue to avoid the area, with trams and other public transport also affected.

We've been hearing more from Ponds Forge Sports Centre, where dozens of residents from the Gateway apartments are staying after being evacuated late last night.

Venue manager Lorenzo Clark said he and his staff have been trying to make people "as comfortable as they can be".

Reflecting a view we heard from some of the residents earlier, Mr Clark said most people were in a "light-hearted frame of mind".

"The citizens of Sheffield are resilient and they've been quite buoyant," he said.

"It's a very serious incident and the emergency services are clearly doing the best they can."

Mr Clark said he had had no indication as to whether or not the residents would need to stay overnight again this evening, but added: "We're putting plans in place so we can feed everybody we've got here tonight as well if needs be.

"We're calling upon colleagues as well to come in and be available for an overnight stay."

We've had an update from South Yorkshire Police in the last few minutes, in which they have confirmed specialist officers are "negotiating" with a man inside the Gateway apartments in Sheffield.

The force said the man is "alleged to be in possession of weapons and poses a risk to himself" and asked people to continue avoiding the area.

The statement continued: "We understand the disruption and impact this incident is having on our communities, those affected by the evacuation, roads closures and those concerned for loved ones in the area.

"Our aim is to bring the incident to a close safely and get everyone and their families back to their homes as soon as possible."

Erin, who was moved to Ponds Forge sports centre at 20:30 GMT last night, described the evacuation as a "stressful situation".

"All we had time to grab was our phones, we've literally got the clothes we're standing in and our phones," she told BBC Radio Sheffield.

"We had blow-up beds and pillows provided, we initially thought it would just be an hour."

She added: "We've got no idea what's going on and obviously all of our belongings are in the building."

Oliver King, 26, who lives in Gateway apartments, said police pointed guns up at the building as the incident started to unfold last night.

"We decided to get out of there because it was quite scary," he said.

Oliver and his partner decided to check into a hotel with their dog, Sky, at around 03:00 GMT after being evacuated.

"It's really inconvenient and upsetting for people who haven't got access to their medication," he added.

"You've got diabetics who haven't got access to insulin, it's a little scary for those individuals."

All eyes are on the Gateway apartments building in Sheffield, specifically looking at the top floor.

There is an open window with a towel hanging out of it.

On the floor below there are a number of armed police officers dressed in black standing on a balcony looking towards it.
