Sources in Syria reported explosions on Sunday night on a military base of Syrian President Bashar Assad north of Homs, Syria. According to some reports, Israel is responsible for the attack.
Syrian state television says there are several explosions in Hama province and authorities are investigating the reaction.
Former Defense Minister Avigdor Lieberman said Israel will maintain freedom of movement in Syria.
"We have no intention of attacking Russia or interfering in Syrian affairs," Lieberman said at the annual Jerusalem Post conference. "But if anyone thinks it's possible to shoot missiles or attack Israel or even our planes, we'll no doubt react and we'll react very energetically."
The statement came less than a month after a strike at an Iran-based airbase under exclusive Iranian control – an attack attributed to Israel by Syria, Iran and Russia. Several members of the Iranian Revolutionary Guards Corps were killed in the strike. Last Tuesday, Lieberman said Israel could hit Russia-made S-300 air defense systems in Syria if used against Israel.
At the Sunday conference, Lieberman said that Israel has three problems: "Iran, Iran, Iran."
Earlier in April, the Russian military said two Israeli F-15 fighters were air-raiding at a Syrian air base near Homs on Sunday, the Interfax news agency reported. The attack reportedly killed 14 people, at least four of whom were Iranians.
