Asserting that the US is not involved in the process or discussions between parties, an Obama Administration official said it has been "carefully monitoring" the demonstrations in Islamabad.
"We continue to urge all sides to refrain from violence, exercise restraint, and respect the rule of law.
"Peaceful protest and freedom of expression are important aspects of democracy," State Department Spokesperson Jen Psaki told PTI.
However, as the US Embassy in Pakistan has said, the US is in no way involved in the process or discussions between parties, she noted.
"The United States firmly believes all parties should work together to resolve differences through peaceful dialogue in ways that strengthen Pakistan's democratic institutions and rule of law," Psaki said in response to a question.
Cricketer-turned politician Imran Khan and fiery cleric Tahirul Qadri and their supporters have been holding protests in Islamabad for the last two weeks against the government of Prime Minister Nawaz Sharif alleging rigging in the last general elections, which brought Sharif into power for a third time.
