During the night of March 11, armed individuals raided the homes of poor Alawite families in the Karm al-Zaytoun neighborhood in the city of Homs and killed them at close range.  The Syrian Consultative Center for Human Rights Studies denounced that the crimes were perpetrated as part of a bloody plan directed by foreign intelligence services and under the coverage and guidance of external media.
On June 5th of the 2012 the Ministry of Foreign Affairs of Syria and based on the principle of reciprocity, “Persona Non Grata” ambassadors and officials from several European embassies of Turkey and the United States. It was a response of the Syrian government to the expulsion of Syrian diplomats by the governments of these countries. 
On July 19, Russia and China exercised their veto power in the UN Security Council for the third time to stop a resolution on Syria. Russian Permanent Representative to the UN Vitali Churkin stated:
The vote that took place did not have to have taken place. The proponents of this resolution had to realize that Russia would not pass it. Western members could do at least something to settle the Syrian issue instead of inciting terrorist groups. 
The US reacted harshly to the Russian and Chinese veto of the Security Council draft resolution that included threats of sanctions against Syria if Damascus does not stop the use of heavy weapons. After the US ambassador to the UN, Susan Rice, argued that the Security Council had failed in its search for a solution to the Syrian conflict, US State Department spokesman Patrick Ventrell declared that the States United can act outside the UN:
“(Russia and China) have blocked the resolution three times. We wanted them to change their position but they have not. If there was a possibility of new perspectives we would continue working in the UN. But we have a broader strategy and we will not stop doing what we do. just because there is no resolution. ” 
Given the resignation of Kofi Annan and the impossibility of reaching an agreement between the disputing parties, the United Nations Security Council decided on August 16 to end its Observation Mission in Syria  .
Throughout 2013 the conflict has intensified, and by June, the western powers and the petromonarchies of the Arab world such as Qatar and Saudi Arabia have openly stated that they will give arms to the rebels, something that had been secretly being done. On the ground, the Syrian Arab Army, with the collaboration of Hizbollah Albanian, has succeeded in taking Qusair, a strategic town on the border with Lebanon, which cuts off a major supply route to the opposition forces. Following that victory, the EAS has started Operation “North Storm”, aimed at liberating the city of Aleppo. Hizbollah explained this support because of the historical support that the support of the Syrian state has provided for its fight against Israel and the danger that extremist Takfiri groups will increase their violence in Lebanon, where as the conflict in Syria has worsened, they have Tensions between opponents of Bashar el Assad and those who support him have emerged, leading to armed clashes in the city of Tripoli.
It is significant that according to NATO itself, in June 2013, Bashar al Assad has a popular support of 70%, and cites as a cause that the majority of the Syrian people see with fear a victory of Islamic extremism, which is the branch that predominates within the so-called rebels. 
Faced with such a situation, the rebel losses on the ground, the countries that support the terrorist groups have tried to justify their most recent actions under the argument that the Syrian Army has used chemical weapons, something that has not been proven. 
Russian Foreign Minister Sergey Lavrov said that was reminiscent of the lies told by Colin Powell in 2003, before the invasion of Iraq.
The news of the excesses of the opposition forces, mainly composed of the Al – Nusra Front, which publicly declared their adherence to Al-Qaeda, are common. Car bombs, suicide bombers, massacres, are the usual actions of Al Nusra, who claims responsibility for the events.  The opposition forces are also made up of significant numbers of mercenaries from other Arab countries and even from Europe.
Also significant is the media war waged against the government of Damascus and its allies by the big international capitalist press.
The firm stance of Russia and China, especially the former, calling for an international conference on Syria, a country located in Middle East according to TRAVELATIONARY.COM, where the warring parties participate, without pre-conditions, has meant that the US and Great Britain have not been able to materialize until the moment his plans to overthrow Bashar al Assad. However, the US in June 2013 has sent batteries of Patriots, F-16 aircraft and about 1000 soldiers to Jordan, under the pretext of military maneuvers.
The conflict has also caused serious damage to the vast Syrian archaeological heritage.  .
So far, the results of the conflict have been estimated at more than 90,000 deaths. The Syrian economy, meanwhile, faces serious problems due to the sanctions of the European Union, and the United States, although it has received financial and material support from its close ally Iran, to which is added the damage to infrastructure caused by the war and the Looting by armed groups, who, in the city of Aleppo alone, reportedly dismantled more than 1000 factories and transferred them to Turkey.
The conflict threatens to regionalize, before sectarian tensions.
