Ferguson is a top story on Iranian media this morning. English-language Press TV has dropped some of its regular news coverage to dedicate all of its morning programming to "live" video from the protests.
The channel mentions demonstrations sweeping American cities including New York, where it says "angry protesters reached the UN headquarters". The front pages of a number of Iranian dailies are splashed with pictures of violence at the protests. Keyhan newspaper says there is "rebellion in 90 American cities".

The protests also reached Washington DC, where a group of demonstrators gathered before the White House.

How the jury got there
The New York Times has an in-depth look at the evidence the grand jury considered before deciding Officer Darren Wilson would not face criminal charges. Amid conflicting witness accounts, forensic evidence, and a wealth of police reports, the article suggests that in the end, "it all came down to Officer Darren Wilson himself".
American 'self-delusion'
BBC Monitoring
Ferguson is a front-page story in the German press, too. Uwe Schmitt, the former Washington correspondent of Germany's centre-right daily Die Welt, writes that Ferguson is a "predictable explosion", given the combination of a "grotesquely over-armed police force" with a black community "untouched by economic recovery, doing badly-paid jobs or having long fallen out of labour market, filling the prisons in proportions that defy probability".
He accuses many Americans of "self-delusion" when they ask how such violence can recur, while abroad "people shake their heads unsurprised, either in mourning or glee".

There's been confrontation outside Ferguson City Hall where a police vehicle was burnt earlier and tear gas still hangs in the air. There's a heavy police presence with several armoured cars and vehicles.
There is tension as police try to move people from the area - officers are saying anyone standing in the street will be subject to arrest. Some are giving chase to people in the surrounding streets and tonight they have dogs with them. A police helicopter is hovering overhead with a spotlight.
'Justifiable homicide'
Darren Wilson has become one of hundreds of police officers in the US whose use of force is deemed justifiable under the law, Time reports.
"The Federal Bureau of Investigation recorded 410 'justifiable homicides' in 2012, and that is self-reported by states with varying degrees of rigor. The actual count is likely higher," it adds.
Pepper spray
In Portland and Denver police have reportedly resorted to pepper spray to disperse protesters, according to the AFP news agency.

Arrests
Several people have been arrested in Ferguson overnight. One woman was taken into custody after protesters threw what appeared to be smoke bombs, flares and frozen water bottles at police, AP reports. Two others were arrested for failing to heed police instructions, the agency adds.
The Guardian's Jon Swaine delves deeper into what state prosecutor Bob McCulloch said in his statement on Monday, when he announced that Darren Wilson would not be charged over the shooting of Michael Brown. The journalist gives his interpretation of what the prosecutor really meant, particularly his criticism of the protesters and the media.

There's been confrontation outside Ferguson City Hall where a police vehicle was burnt earlier and tear gas still hangs in the air. There's a heavy police presence with several armoured cars and vehicles.
There is tension as police try to move people from the area - officers are saying anyone standing in the street will be subject to arrest. Some are giving chase to people in the surrounding streets and tonight they have dogs with them. A police helicopter is hovering overhead with a spotlight.
'Justifiable homicide'
Darren Wilson has become one of hundreds of police officers in the US whose use of force is deemed justifiable under the law, Time reports.
"The Federal Bureau of Investigation recorded 410 'justifiable homicides' in 2012, and that is self-reported by states with varying degrees of rigor. The actual count is likely higher," it adds.
Pepper spray
In Portland and Denver police have reportedly resorted to pepper spray to disperse protesters, according to the AFP news agency.
