National Security Council spokeswoman Bernadette Meehan says the Egyptian government has a responsibility to create an atmosphere where all Egyptians "can exercise their universal rights, including free assembly, expression, and press." She says the U.S. condemns all acts of violence and any "incitement to violence."
A string of attacks on Monday killed nine members of Egypt's security and military forces. The attacks appeared to be retaliation by Islamic militants after more than 50 supporters of ousted President Mohammed Morsi were killed in clashes with police Sunday.
Egypt's military forced the democratically-elected Morsi from office earlier this year.
