He did not produce evidence of this.
Syria accidentally shot down a Russian military aircraft, on Monday killing all 15 crew members, when its air defences swung into action against an Israeli missile strike, Russian and Israeli forces said on Tuesday.
While Israel will very likely continue to strike targets deemed an "intolerable risk" to the Jewish state, Israeli pilots will have to remember the warning Russian Defense Minister Sergei Shoigu told his Israeli counterpart Avigdor Liberman: "Such actions will not be left unanswered". On Tuesday, the IDF expressed " sorrow" for the deaths of Russian airmen, but once again said the responsibility lies with the "Assad regime".
"On behalf of the Syrian people and by my name, we express our deep condolence over the fall of the Russian jet on the Mediterranean, causing the martyrdom of the Russian heroes who were doing their noble duties along with their colleagues of the Russian military forces in the fight against terrorism in Syria", Assad said in his letter of condolences to Putin.
Russia, the biggest outside backer of Syrian President Bashar al-Assad in his fight against rebels, has been preparing for an offensive on the city of Idlib, which is controlled by rebels and now home to about 3 million people.
The delegation is also supposed to further acquit themselves of any blame and inform Moscow of "continuous Iranian attempts to transfer strategic weapons to the Hezbollah terror organization and to establish an Iranian military presence in Syria".
In another speech on Thursday morning, the Hezbollah leader declared that the dozens of Israeli strikes aimed at preventing it from acquiring rockets with highly accurate targeting capacity had failed because it had "already been achieved".
Israel worries Hezbollah has been improving its capabilities and acknowledged carrying out scores of strikes in Syria, majority believed aimed at halting suspected arms shipments for Hezbollah.
"If Israel imposes a war on Lebanon, Israel will face a fate and a reality it has never expected on any day", he warned.
"We will do everything, everything that is required, in order to defend the security of Israeli citizens. We will do everything so as not to harm anyone we do not intend to, God forbid", Bennett told Army Radio in a separate interview.
But with an inaccurate system responsible for downing one of their military planes, the idea might be brought up again with Damascus. "We acted as we always act".
In a Tuesday phone call to Putin, Israeli Prime Minister Benjamin Netanyahu said Israel was ready to provide Moscow with all relevant information regarding the incident, according to a statement issued by Netanyahu's office.
