Britain's Minister for the Middle East, Hugh Robertson, condemned the violence that took place in Egypt on the third anniversary of the 25 January revolution.
In a statement published on the FCO's website, Robertson said: "The UK condemns the large-scale violence in Cairo and other parts of Egypt on 25 January that has resulted in the deaths of 49 protesters. We call on all sides to act proportionately at all times."
The minister welcomed a call by the interim President Adly Mansour for the Prosecutor General to release detainees who have no criminal evidence against them.
He urged the interim government to implement the fundamental rights outlined in Egypt's constitution, "including by allowing peaceful protest".
Robertson concluded his remarks saying; "The UK continues to believe that the only sustainable way for Egypt to address its current challenges is through an inclusive political process which allows all Egyptians a voice in the country's future. The UK stands ready to support the Egyptian people in achieving this."
