The sound of a protest outside her window wakes Brennah Hammar in the middle of the night.


Tear-gas creeps into her apartment complex, Gray's Landing, which is located across from an Immigration and Customs Enforcement (ICE) building in Portland's South Waterfront neighbourhood.


For months, the area has become the site of nightly clashes between federal agents and protesters, dressed in black, who are opposed to immigration arrests.


It's like a war zone, Ms. Hammar, 57, says about her street. Several other residents spoke to BBC News about the unrest, which is centred on just one city block, as tensions have boiled over and put the city in the national spotlight.


There are times I've had to have a gas mask on inside my own home, she says, demonstrating how she now wears her mask to sleep.


President Donald Trump says he wants to send in the National Guard to protect the officers and federal buildings, making Portland the latest test case in Trump's plan to deploy troops to places - mostly Democratic-run cities - that he says are plagued by crime.


Portland is burning to the ground and is plagued by insurrectionists all over the place, he says.


But a federal judge has disagreed and temporarily halted Trump's plans for Portland, stating the president appeared to have exceeded his constitutional authority.


Trump's comments have also been widely mocked as hyperbole by the city's 635,000 residents.


However, for those living in this apartment complex, there is a daily battle on their doorstep, although they disagree over who is to blame for the violence.


Some building residents blame Antifa, a decentralized leftist movement opposing far-right causes that Trump has designated a domestic terrorist group.


Gray's Landing neighbours sympathetic to the more extreme protesters have been allowing them to enter the building, leading to confrontations in hallways, residents say.


And some, who have gone outside at night, have been attacked or threatened, according to footage Ms. Hammar filmed and showed to BBC News.


Mayor Keith Willis blames federal agents for inciting the crowd, calling for an investigation into their actions.


Whether blame lies with the protesters or federal agents, the violence has already changed the community.


The Cottonwood School, located next door to the ICE building, relocated after munitions kept being found in the playground.


During the BBC's daytime visit, one resident was seen carrying his two pet rats and screaming insults at ICE agents posted outside the federal building.


Get back in your pen, pig! yelled the man, as bike commuters stopped by to observe the scene.


Gray's Landing resident Cindy Colgrove, 63, described it as 115 days of hell since protests against Trump intensified.


I only come out during the day, says Ms. Colgrove, noting that the more violent protesters tend to come out at night.


Ms. Colgrove, who has been attacked for her pro-police stance, shows off weapons she carries for safety: a can of bear mace and a stun gun.


Fellow resident Mai Tai Boyd, 44, disagrees with the assessment that their building has been abandoned by local officials, arguing against deploying troops into the city.


In other parts of Portland, life continues as normal, with events such as the Portland Marathon taking place without incident in the same vicinity.


Most Portland residents blame Trump for the unrest; many feel he has inflamed tensions in the past. Hammar, however, supports Trump’s proposition, saying the city's failing response leaves her feeling like collateral damage in this ongoing turmoil.
