"We are deeply troubled by reports of deaths, widespread arrests, beatings, and harassment of protestors by security forces of the Government of Zimbabwe," the senators said in a statement.
"The Zimbabwean people have the constitutional right to protest peacefully and express themselves regarding developments in their country.
"Government officials and security forces must respond with professionalism and respect for human rights and the rule of law
"We also call on the Government of Zimbabwe to rescind the directive ordering communication service providers to cut or restrict access to social media, internet, and telephone services.
"Such abrogations of constitutional and basic legal rights are not what the people of Zimbabwe were promised under President Mnangagwa."
