Egypt's military council has said the decision to dissolve parliament must be upheld.

埃及军事委员会称，支持总统下达的解散议会的决定。

The military closed parliament last month after a court ruling.

Its latest intervention¹ is seen by some as a challenge and warning to the president, who was sworn in barely a week ago.

It could be the first confrontation²（对抗） between the military and the president since Mr Mursi's election.

On President Mursi's orders, the speaker has convened³ a meeting of parliament on Tuesday.

Crowds were gathering⁴ in Tahrir Square ahead of the meeting called for 10:00 (08:00 GMT) in defiance⁵ of（不顾，无视） the military's decision.

The Muslim Brotherhood⁶ - Mr Mursi's power base, which has the biggest bloc⁷ of seats in parliament - said it would participate on Tuesday "in a million-man march in support of the president's decision and reinstating parliament".

The military council said it was confident "all state institutions" would respect the law and constitution.

The BBC's Jon Leyne, in Cairo, says the political truce⁸ in Egypt appears to be over.

It is unclear how events will unfold as the situation - with the new president elected without a new constitution being drafted, and the parliament theoretically dissolved - is unprecedented⁹, analysts¹⁰ say.
