Egypt's army and government will offer to free some Muslim Brotherhood members from jail, unfreeze the group's assets and give it three ministerial posts in a bid to end the country's political crisis, a senior military source said on Monday.

"The initiative will be made so that we can end the crisis and have the Brotherhood end their sit-ins," the military source told Reuters. A political source familiar with the proposal confirmed the details.

News of the compromise come as international envous were in Cairo trying to defuse the crisis.  U.S. Deputy Secretary of State William Burns began his trip with a visit to Egypt's Muslim Brotherhood leader Khairat El-Shater in jail early on Monday, a top U.S. diplomat said.,

Brotherhood spokesperson Gehad el-Haddad confirmed the meeting but said that Shater cut it short, saying that the international enovys should be talking to Morsi.

U.S. senators John McCain and Lindsey Graham were expected to arrive in Cairo on Monday evening. "I want to keep the aid flowing to Egypt, but it has to be with the understanding that Egypt is going to march toward democracy, not toward a military dictatorship. And that's the message we're going to send," Senator Graham said in a CNN interview before the trip.
