David Cameron has promised a “comprehensive strategy” to win MPs’ backing for bombing Islamic State militants in Syria as well as Iraq.
The prime minister told the Commons the Paris attacks had strengthened the case for air strikes, suggesting there could be a fresh vote on the issue.
He wanted to “do the right thing for our country”, and hit the “head of the snake” of IS in Raqqa, Syria, he said.
MPs rejected strikes against Syrian government forces in a 2013 vote, reports the BBC.
Labour leader Jeremy Corbyn said any military response should have the support of the international community and legality from the United Nations.
Two years ago, MPs voted against possible UK military action against President Bashar al-Assad’s government in Syria.
Parliament later approved British participation in air strikes against Islamic State extremists in Iraq, which have been ongoing ever since.
Cameron has promised British air strikes against IS will not be extended to Syria without Parliament’s consent – and said he would only hold another vote when he was sure of a “consensus” among MPs.

Downing Street has stressed it is not setting out a timetable publicly for a Commons vote yet, says BBC political correspondent Chris Mason.
An “important first step” would be setting out his case in a personal response to a recent Foreign Affairs Committee report, the prime minister said.
