A military coalition led by the US, ready to intervene in case the Syrian regime uses chemical weapons against rebel forces, could include Israel, Maariv has reported.

The US is ready to take military action “within days” if chemical weapons are used, according to reports.

“It won’t require major movement to make action happen. The muscle is already there to be flexed,” a US official told The Times. “It’s premature to say what could happen if a decision is made to intervene. That hasn’t taken shape, we’ve not reached that kind of decision. There are a lot of options, but it [military action] could be launched rapidly, within days.”

Countries involved in the combined force could include the UK and other European allies, The Times said. Maariv reported that Turkey and Jordan could also be involved.

These reports come after Israeli Prime Minister Benjamin Netanyahu told Israel’s National Public Diplomacy forum on Tuesday that the country is “closely monitoring” developments in Syria.
