MOSCOW (Reuters) -Syrian President Ahmed al-Sharaa told Russian President Vladimir Putin on Wednesday he would honour all past deals struck between his country and Moscow, a pledge suggesting Moscow's two main military bases in Syria are safe. Sharaa, who once headed the Syrian branch of al Qaeda and who toppled predecessor Bashar al-Assad, a close Russian ally, late last year, was speaking at the start of Kremlin talks with Putin, his first visit to Russia since coming to power.
