Syrian vice president Farouk Al-Sharaa has made his first public appearance in several weeks, ending rumours that he had defected.
Mr Al-Sharaa was last seen at the funeral of four top Syrian government officials who were killed in a blast in Damascus on July 18.
Since then, speculation has circulated that he had defected to Jordan in what would have been a blow to Bashar Assad's regime.
Jordan and Mr Al-Sharaa's office repeatedly denied he had defected.
On Sunday, reporters saw Mr Al-Sharaa exit his car and walk to his office for a meeting with Alaeddin Boroujerdi, head of Iran's powerful parliamentary committee on national security and foreign policy.
Reporters at the scene said Mr Al-Sharaa looked serious and steered away from those covering the meeting. He did not make a statement.
