We're going to wrap up today's live blog Egypt coverage. Here's a summary of where things stand, with the most recent developments at top:

• The White House said it was considering changes to its aid package for Egypt in reply to the mass killing of civilians. No decision has yet been taken, however, an Obama spokesman said.

• Defense secretary Chuck Hagel said that the US lacks a real carrot or stick to turn Egypt in any one direction. "Our ability to influence the outcome is limited," Hagel said. "It's up to the Egyptian people."

• In a damning report published Monday, Human Rights watched called the killing of civilians in Egypt "the most serious incident of mass unlawful killings in modern Egyptian history." In all an estimated 1,000 people, mostly Morsi backers, have been killed in clashes and executions in the last week. Activist groups called for an investigation into the killing of 36 Morsi supporters while they were in state custody.

• The lawyer of Hosni Mubarak said the former president could be freed within 48 hours, although other reports said any such release would take weeks. An Egyptian court was said to order that Mubarak be released.

• 25 off-duty police officers were killed in Sinai in an ambush by unidentified militants. The militants stopped two buses carrying the officers, removed them and executed them. The specific motive in the crime was a subject of conjecture.

• State prosecutors have brought new charges against President Mohamed Morsi for an alleged role in "violent acts" committed during protests last December, state news reported.

• The EU is meeting today to "urgently review" its relations with Egypt, British foreign secretary William Hague said.
