Egypt's top military council says the army chief and defense minister Abdul Fattah al-Sisi should listen to what it said were the calls of the people and stand for president. The statement said field marshal al-Sisi had thanked the military leadership for allowing him to respond to the call of duty. He's now expected to announce his candidacy within days. Orla Guerin reports from Cairo.

The softly spoken former intelligence chief has no experience of war, but has shown himself to be a skilled political tactician. He became a national hero for many after he ousted the Islamist President Mohamad Morsi in a popularly backed coup last July. On Saturday, huge crowds gathered in Tahrir Square, urging him to stand in a state-sponsored display of support. But his critics were driven off the streets by the security forces and about 60 people were shot dead in clashes.

The UN mediator at the Syrian peace conference Lakhdar Brahimi, says there has been no breakthrough in attempts to arrange aid convoys to the besieged city of Homs. A joint negotiating session on establishing a transitional government also made scant progress. The BBC's Bridget Kendall heard what Lakhdar Brahimi had to say about the attempts to get aid to Homs.

He said he thought the Syrian government was willing, but the danger of snipers and other problems meant it wasn't easy. He noted Homs was only one of many parts of the country where people found themselves under siege either from Syrian government forces or armed groups. The good news though is that the two rival delegations from Syria are still talking even though they clearly had a tense standoff this morning over the question of Syria's political future. One delegate called it a dialogue of the death.
