Israel carried out a wave of heavy airstrikes across Syria as its troops advanced deeper into the country, a Syrian opposition war monitor said Tuesday, and the Israeli defense minister announced that his forces had destroyed Syria's navy.

There was no immediate comment from the insurgent groups -- led by Hayat Tahrir al-Sham, or HTS -- that have taken control of Damascus.

The strikes are part of Israel’s campaign to destroy weapons left behind by ousted President Bashar al-Assad’s forces.
