Maryland police arrested dozens of demonstrators on Saturday (July 16) who were protesting over the fatal shootings of two black American men by police. <br /> <br />Police arrested 65 people in Baltimore, Maryland mostly for misdemeanors for blocking traffic, NBC said <br /> <br />Authorities grappled with a wave of demonstrations against police use of force that has swept the country in the past weeks after the killing of Philando Castile, 32, in a St. Paul, Minnesota, suburb, and Alton Sterling, 37, in Baton Rouge. <br /> <br />The protest took place as Baltimore awaits a decision in the trial of a police officer charged in the 2015 death of black detainee Freddie Gray, which then triggered protests and rioting. <br /> <br />At a spontaneous march in Dallas on July 7, a U.S. military veteran shot and killed five police officers, sending a chill through law enforcement as well as those involved in the mostly peaceful demonstrations. <br /> <br />Baltimore police received a warning from the Federal Bureau of Investigation on Thursday (July 14) that local gangs were targeting police, Police Chief Kevin Davis said. <br /> <br />With protests hitting many U.S. cities, the deadly ambush of Dallas police, and the ever-present threat of gun violence, four countries have urged citizens to be on alert if visiting the United States, and some black travelers are worried about making the trip. <br /> <br />The Bahamas, Bahrain, New Zealand and the United Arab Emirates have warned citizens to be on guard if visiting U.S. cities rocked by sometimes violent protests.
