U.N. Secretary-General Ban Ki-moon issued a call to Syria's embattled President Bashar al-Assad Sunday, urging him to stop killing his people.

In a keynote address at a conference focused on democracy in the Arab world, Mr. Ban said “the path of repression is a dead end.”

Mr. Ban told those in attendance in Beirut that the Arab world's revolutions show that people there are no longer content with one-man rule.

The United Nations says more than 5,000 people have died in Syria since the uprising began last March. Meanwhile, Syrian authorities blame what they call “armed terrorists” for killing some 2,000 members of the security forces.

In an interview to be broadcast Sunday in the U.S. , the emir of Qatar, Sheikh Hamad bin Khalifa al-Thani, proposes sending Arab troops to Syria to halt the bloodshed in that country.

The emir is the first Arab leader to publicly support Arab military intervention in Syria, where protesters are demanding President Assad's resignation. The emir said the Arab League observer mission, sent to Syria on December 26, has made mistakes, and that U.N. assistance is needed to improve the monitoring of the Damascus government.

In the latest clashes Saturday, the British-based Syrian Observatory for Human Rights said several people were killed in different parts of the country, including a 13-year-old boy and a 27-year-old man in the flashpoint city of Homs.
