Crowds of protesters have amassed in cities across the US to denounce President Trump, in the largest nationwide show of opposition since the president took office in January, BBC reported.

The "Hands Off" protest planners aimed to hold rallies in 1,200 locations, including in all 50 US states. Thousands of people turned out in Boston, Chicago, Los Angeles, New York and Washington DC, among other cities, on Saturday. 

Protesters cited grievances with Trump's agenda ranging from social to economic issues. 

Coming days after Trump's announcement that the US would impose import tariffs on most countries around the world, gatherings were also held outside the US, including in London, Paris and Berlin, according to BBC.
