The only interest we have is Israel's and its population's security, says Saar at a press conference on Monday.
We attacked strategic weapon systems, such as remaining chemical weapons or long-range rockets and missiles, so they wouldn't fall into the hands of extremists.
He gave no details about when or where the attack would have taken place.
Even the UK-based Syrian Human Rights Observatory (SOHR) reports that Israel attacked Syria. Israel targeted military sites, including weapons depots, according to SOHR chief Rami Abdel Rahman.
Late on Monday, SOHR says at least 100 attacks were carried out during the day. Among the targets was the Barzah research institute, and the reason for the attack was "to destroy the former regime's military capability", according to Rahman.
Israel has attacked Syria from the air hundreds of times in recent years, against what is said to be military targets linked to Iran and the Shia militia Hezbollah, close allies of the ousted President Bashar al-Assad.
Syria agreed to dismantle its chemical weapons in 2013 after the government was accused of an attack near Damascus that killed hundreds of people. Many believe, however, that the country has retained parts of the weapons and has been accused of using them again in the following years.
