Syrians are looking to the world in their hour of need and "we cannot let them down," U.S. Secretary of State Hillary Clinton said Friday at an international conference on Syria held in Tunisia.

The dozens of countries represented at the conference, Clinton said, are united in their demands: Syrian President Bashar Assad must allow much-needed aid to his people and silence his guns or face more isolation and pressure.

But debate continues over what other steps countries in the region could take.

The U.S. evacuated the staff of its embassy in Damascus earlier this month due to security issues. But that hasn't stopped Robert Ford, the U.S. ambassador to Syria, from using social media to keep in touch with events on the ground, and to try to shape them.

Russian anti-corruption crusader Alexei Navalny has been the victim of many dirty tricks by pro-Kremlin media.

But when the U.S. government-funded Voice of America published an online interview that had him criticizing other Russian opposition figures, Navalny quickly tweeted that the interview was a fake.

"It seems the VOA has gone nuts," he wrote to his Twitter followers.

China's Vice President Xi Jinping visits the White House Tuesday. While in Washington, Xi will discuss a broad range of bilateral, regional and global issues. He'll also travel to Iowa and California. Xi is widely expected to become China's next president.

In a rapidly escalating dispute between allies, 43 people, including 19 Americans, are to face trial in Egypt for their work in promoting democracy. They include the son of U.S. Transportation Secretary Ray LaHood.

Sam LaHood was running the Cairo office of the International Republican Institute. The case against him and others has caused a furious reaction in Washington — with lawmakers threatening to hold up U.S. aid to Egypt.

The U.N. Security Council failed again Saturday to take decisive action to stop the escalating violence in Syria as Russia and China vetoed a resolution backing an Arab League plan that calls for President Bashar Assad to step down. NPR's Michele Kelemen reports the veto drew intense criticism from the U.S.

For many years, top Egyptian officials coming to Washington could expect a warm welcome, with few points of contention.

But for a group of Egyptian generals now in the U.S., several points of friction are likely to dominate the agenda between the longtime allies.

Egypt doesn't like the new conditions U.S. lawmakers have placed on American aid. And the U.S. is furious with the way Egypt has been treating U.S. groups that promote democracy. At least three Americans have taken shelter in the U.S. Embassy in Cairo.
