US, UK, Germany unite against ISIS
The UK House of Commons will debate today, whether Britain should begin airstrikes against ISIS targets in Syria.
On 1 November, the US decided to deploy special operations troops to Iraq to combat ISIS in the region, while Germany decided to send non-combat forces to aid allies in the conflict.
These events indicate a significant escalation of the 4 year conflict in Syria.
Mar 2011: What is the Syrian Civil War about?
An uprising began in Syria in 2011 against alleged atrocities committed by President Bashar Assad's regime.
"Moderate" rebel forces (supported by the US) began an armed conflict to overthrow the government.
In 2013, ISIS militants declared a "caliphate" extending from Syria into Iraq and began large-scale attacks in Syria.
All three parties have since been at war with each other for territorial control.
30 Sep 2015: Russia begins airstrikes against ISIS in Syria
Russia began airstrikes in Syria in late September.
Syria is Russia's closest ally in the region and Putin's decision to conduct airstrikes was indicative of direct assistance to the Assad regime
Russia asserted that there is no "moderate" rebel force and that the only solution to the Syrian conflict lies with President Bashar Assad retaining power in the war torn country.
13 Nov 2015: ISIS and the Paris attacks
On Nov 14, ISIS claimed responsibility for one of the biggest attacks in Paris that killed over 130 people in a spate of shootings and suicide bombings.
The attacks left the EU shaken and accentuated the transnational nature of the threat posed by the Islamic State.
France has since appealed to the EU and NATO to join the airstrikes in Syria against the ISIS.
Fact: Why is Syria under the scanner?
In light of the Paris attacks, the EU and NATO now see a threat posed by ISIS fighters who may infiltrate EU nations as Syrian refugees in order to carry out attacks.
1 Dec 2015: US deploys ground forces against ISIS
US Defence Secretary Ash Carter said that the US is to deploy 200 special operations troops in Iraq to combat the ISIS forces in the region and neighbouring Syria.
The move is said to have been made in agreement with the Iraqi government to aid Iraqi security forces and Kurdish peshmerga forces.
The troops are to conduct raids, gather intelligence and capture ISIS leaders.
1 Dec 2015: Germany also joins the fight
German Chancellor Angela Merkel's cabinet approved plans for Germany to join the fight against ISIS in Syria.
The move comes as response to the 13 November attacks in Paris.
Germany will not join the airstrikes but will send reconnaissance jets, refuelling aircraft, a frigate and up to 1200 soldiers to the region.
The move steps away from Germany's post-WW2 policy of avoiding foreign conflicts.
2 Dec 2015: US, UK, Germany unite against ISIS

3 Dec 2015: MPs authorise Syria air-strike
After a prolonged debate in the House of Commons, British Members of Parliament voted in favour of David Cameron's proposition to conduct airstrikes in Syria against ISIS, in spite of opposition from Jeremy Corbyn's Labour Party.

The T-90 is capable of defending itself from anti-tank missiles that rebels and ISIS fighters use.
Reports indicate they will be manned by Syrian soldiers.
