Syrian media reports say Israeli warplanes have carried out dozens of attacks across the country, including in the capital, Damascus.
The UK-based Syrian Observatory for Human Rights (SOHR) said there were more than 100 strikes on military targets.
A research centre with suspected links to chemical weapon production was among the sites hit, according local media reports.
Israel says it is acting to stop weapons falling “into the hands of extremists” following the overthrow of the Assad regime.
