Several members of the US Congress sent a message to Secretary of State John Kerry asking him to publicly address the human rights violations in Egypt, AP reported on Tuesday.
The letter also asked Kerry to emphasise the need for the interim government to protect minorities in Egypt, including Coptic Christians.
According to the AP report, Senators Bob Corker and Lamar Alexander of Tennessee, and Roy Blunt of Missouri, cited the recent attacks targeting Coptic churches and other individuals.
In their letter to Kerry, the three said: "Egypt's Christian minority and their ability to worship are in danger. The situation warrants a clear US response."
