Israel denied on Tuesday that its forces had penetrated into Syrian territory beyond the buffer zone with the Israeli-occupied Golan Heights, after Syrian sources said the incursion had extended to within 25 km (15 miles) of the capital Damascus.

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.

A visual guide to the latest developments after Syrian rebels toppled President Bashar al-Assad 13 years after the start of the country's civil war.

There are Turkish-backed rebels and Sunni Muslim jihadists in the north, Kurds ruling over much of Syria’s east, and Jordan-backed militants in the south, among others. These groups fought a civil war against Assad for almost 14 years and will now contend to shape the country’s future without him.
