Supporters of Egypt's ousted president Mohamed Morsi on Friday slammed US Secretary of State John Kerry after he said the military was "restoring democracy" by deposing the Islamist leader.

"Is it the job of the army to restore democracy?" asked Gehad El-Haddad, a spokesman for Morsi's Muslim Brotherhood in a statement.

"Does Secretary Kerry accept Defence Secretary [Chuck] Hagel to step in and remove [US President Barack] Obama if large protests take place in America?

"Will the US army freeze the constitution and dismantle Congress and [the] Senate? Can they appoint a president that they solely choose?"

El-Haddad's statement came after Kerry told Pakistan's Geo television on Thursday that the Egyptian military had acted to save the country from violence by ousting Morsi on July 3 after major nationwide protests.

Since Morsi’s ouster by the military on 3 July Washington has trodden carefully, stopping short of labeling the move a “coup.” Under US law, such a decision would require the Obama administration to cut off its annual $1.5 billion of aid to Egypt, most of which is military aid.

US officials have been in dispute over how to assess the situation in Egypt.

On Wednesday, the US Senate voted 86-13 against a proposal to halt aid to Egypt and to allocate the money instead for building bridges at home. The decision followed a proposal by a potential Republican presidential candidate challenging the Obama administration's refusal to label Morsi's overthrow a military coup.

"The military was asked to intervene by millions and millions of people,” who feared the country could descend into chaos, Kerry told Geo.

"And the military did not take over, to the best of our judgement -- so far. To run the country, there's a civilian government. In effect, they were restoring democracy," he added.

El-Haddad called Kerry's comments "alarming,” and accused the US administration of being "complicit in the military coup".

"The American people should stand against an administration that is corrupting their values in supporting tyranny and dictatorship," he added.
