Edward Snowden, the former US intelligence contractor wanted by Washington on espionage charges is spending the night at an airport in Moscow after arriving from Hong Kong. Reports say he's got a ticket to fly to Cuba on Monday, and the Ecuadorian government says he's asked for asylum in Ecuador. The US State Department says Mr. Snowden's passport has been revoked and he should not be allowed to travel internationally. Mike Rogers, the chairman of the House of the Representatives intelligence committee, said Mr Sonwden's actions had already had security implications. He has taken information that does not belong to him - it belongs to the people of the United States - he has jeopardized our national security. Clearly the bad guys have already changed their ways. Remember, these were counterterrorism programs essentially; and we've seen that bad guys overseas, terrorists who are committing and plotting attacks on the United States and our allies have changed the way they operate. We've already seen that.

The head of the arm forces, General Abdel-Fattah al-Sisi, he is also the Defense Minister, made the warning ahead of rallies against President Mohammed Morsi due next weekend and after demonstrations in support of the president. Khaled Ezzelarab is in Cairo. When the Defense Minister says that the army will not allow an attack on the will of the people, this phrase is usually used by President Morsi and his Islamist allies to indicate the majority that they have won in several elections. However, the Defense Minister said that the army will not remain silent as the conflict slides into uncontrollable conflict, and that everyone should reach a compromise and this is being interpreted by Morsi's opponents as pressure on the president to reach a grand bargain with his opponents.
