Israel has carried out over 100 strikes across Syria on Monday, the Syrian Observatory for Human Rights (SOHR) said.
The escalation of attacks on Syria follows the fall of the regime of former Syrian President Bashar al-Assad, who fled to Russia on Sunday.
Two Syrian security sources who spoke to Reuters said Israel had targeted key air bases across the country, destroying infrastructure and dozens of helicopters and planes.
Meanwhile, Mohammed al-Bashir, a key official in the administration overseen by the Islamist group Hayat Tahrir al-Sham (HTS), was appointed as Syria’s new prime minister.
Several reports indicated that he had met HTS leader Abu Muhammad al-Jolani and Mohammed al-Jalali, who served as prime minister under the Assad regime.
Syrians celebrated as insurgents broke into prisons and detention facilities to free tens of thousands of missing men, women and children since the 2011 uprising. HTS chief Ahmed al-Sharaa, known as al-Jolani, was heralded in Damascus for overthrowing the regime in a shock offensive that took just 11 days after more than 13 years of civil war.
Across the country, fighting continued in northern pockets between Turkish-backed factions and the Kurdish Syrian Democratic Forces while a series of Israeli strikes hit government facilities in Damascus and south of the country.
HTS has said it will push on to take final regime strongholds in the coastal cities of Tartous and Latakia, known for their Alawite population and affiliation with the Assad regime, according to reports.
In Gaza, Israeli air strikes hit towns in the centre of the Strip killing at least five people, local media reported while health officials called on the international community to urgently intervene in the north, where the Kamal Adwan Hospital has been repeatedly targeted by Israeli forces.
