Israeli jets strike suspected Syrian biological weapons research center
The center was "flattened out of concern that it might fall into the hands of Islamist extremists fighting to topple the government of Syrian President Bashar Assad," Time reports.
Time also reported that Washington has given a "green light" to Israel to carry out additional raids if it deems them necessary.
As a result of the strikes, Israel has raised security at its embassies and other potential overseas targets in a bid to stop Hezbollah-orchestrated retaliatory attacks.
Only two air strikes had previously been reported - one in Syria on an alleged scientific research center in Jamarya, northwest of Damascus, and one reported by several news organizations that struck a convoy carrying advanced anti-aircraft defense systems toward Lebanon.
An additional two other strikes are believed to have taken place on the same night as the convoy strike, however, including the biological weapons research center, Time reports.
The biological warfare research center was considered to be of particular concern because of the danger of biological agents.
