Iranian President Hassan Rouhani on Tuesday delivered his first English-language TV message to the American people in an interview with CNN's Christiane Amanpour.

Jorge Bergoglio enters a straight leg in the G20 in Saint Petersburg and sends a message to the heavy Catholic Denis McDonough, Obama's chief of staff, to dissuade the U.S. to intervene militarily in Syria.

For Papa Francesco there is a just war, no war is humanitarian appeal for peace in Syria has also convinced Badreddin Ahmed Hassoun, spiritual leader of Sunni Islam that Saturday in the Umayyad Mosque in Damascus, propose, at the invitation of the Pope, a day of fasting and prayer for Syria.

President Obama is trying to convince, we have to wait at least until the middle of next week for the final vote, the Congress to support military action against Syria to punish President Bashar Al- Assad for ordering the killing of hundreds of people with toxic gas.

But what will the punishment consist of ? Military targets hit by U.S. missiles? Bombardment of the presidential palace in the style of Assad Regan bombed the palace of Gaddafi? Fixed targets , which could include airfields? For the moment, we know with certainty that the attack will not follow an operation "boots on ground".

The Egyptian security forces have violently repressed the Muslim Brotherhood camps of al-Nahda and Al-Rabaa Adawiya in the capital, Egyptian sources speak of more than 800 deaths among the ranks of the pro-Morsi supporters, but it is extremely difficult to provide realistic data. The clashes spread outside Cairo too, in particular in the northern city of Minya, where 15 people were killed and a Coptic church was torched, and in the city of Fayoum, where 17people died. On 15/08 supporters of Morsi stormed the government building of Giza and burned with throwing Molotov cocktails. A cameraman Skynews, Mick Deane, and a journalist in the UAE, Habiba Ahmed Abd Elaziz were killed on Wednesday. 

After 25 days of the removal of Egyptian President Morsi, Egypt is still racked by violence raging all over the country. Cairo was the scene of violent clashes between protesters linked to the Muslim Brotherhood who refuse military coup and demanding the return of Morsi. The security forces are stemming protests in the capital, on July 27 the Muslim Brotherhood speak of more than 200 people dead and about 5,200 injured, while according to Egyptian media the number of victims doesn't exceed 75.

The Obama administration has officially accused Assad's army to make use of chemical weapons during the conflict that is raging in Syria for more than two years. Damascus would then passed the "red line" so often mentioned by Obama and would thus have provided the ideal pretext for the U.S. to intervene actively with the supply of weapons to the rebels. The statements by the Deputy National Security Advisor to the White House, Ben Rhodes, of course, have attracted criticism of the other major international actor involved, Russia. Through a tweet, the president of the Foreign Affairs Committee of the Duma, Alexiei Pushkov, categorically denied the claims of Rhodes, as well as filing them lies purpose-built  as it was in the past for Iraq.

If we analyze the situation more carefully arise doubts to which it would be appropriate to provide adequate answers. If, on the one hand, Washington points the finger at Damascus, the doubts about the use of chemical weapons in Syria remain enormous.
