A top U.S. diplomat met early on Monday a jailed senior leader in the Muslim Brotherhood, part of mediation efforts to end the standoff between Egypt’s military-backed government and protesters supporting the ousted president, government officials said.

They said U.S. Deputy Secretary of State William Burns met in prison with Khairat el-Shater, the powerful deputy head of the Brotherhood, the Islamist group from which deposed President Mohammed Morsi hails. Burns was accompanied by the foreign ministers of Qatar and the United Arab Emirates as well as an EU envoy.

El-Shater is charged with complicity in the killing of anti-Morsi protesters.

Burns and the three other diplomats are in Egypt as part of international efforts to end a standoff between Mohammed Morsi’s supporters and the government installed by the military after it toppled the Islamist president in a July 3 coup.
