Syria: Videos show ongoing air strikes on Homs countrysideIBTimes UK

The Syrian foreign ministry has sent letters to the UN Secretary General and head of the Security Council partially blaming Turkey, Saudi Arabia and Qatar for the blasts that took place in the coastal cities of Tartous and Jableh. In the letters, the war-torn country's ministry said: "The blasts were a dangerous escalation by the hostile and extremist regimes in Riyadh, Ankara and Doha."

According to news agency Sana, the letter accused the three countries of meddling in peace talks as well. "They [Saudi, Turkey and Qatar] also seek to derail the Geneva talks and the cessation of hostilities and truce arrangements, as well as turning attention away from the Syrian Arab Army's achievements in the war against terrorism."

The three Arab nations are part of the international coalition that is fighting against Islamic State (Isis) militants, but are supporting rebel groups, battling against Syrian President Bashar al-Assad's regime.

On 23 May, more than 100 people were killed and around 200 others were injured after five suicide bombers triggered blasts in the northern region, while one car bomb each was set off in the coastal cities of Tartous and Jableh. The blasts were claimed by IS (Daesh). Later, reports said that in Jableh, a suicide bomber had walked into the emergency ward of a hospital carrying victims and blew himself blew himself up.

Meanwhile, in a second statement released by the terrorist group, it claimed that the blasts were carried out in a regime held areas "so they [Syrians loyal to Assad] experience the same taste of death which Muslims so far have tasted from Russian [and Syrian government] air strikes on Muslim towns."

The blasts were condemned by the International Committee of Red Cross condemned and UN Secretary General Ban Ki Moon. Soon after the attacks, the latter's spokesperson Stephanie Dujarric said that Ban condemned the attacks and was concerned of the escalation of military activities in Damascus and Homs, which are causing a number of civilian casualties.

The US State Department spokesperson Mark Toner also condemned the terror act. He said, "We will continue to lead the global coalition to degrade and defeat Da'esh so that it can no longer brutalize those who reject its tormented worldview.

"Russia has a special responsibility in this regard to press the regime to end its offensive attacks and strikes that kill civilians, immediately allow relief supplies and to comply completely with the cessation of hostilities."

Russian President Vladimir Putin also condoled the deaths in a message sent to Assad. "The president of Russia once again confirmed a readiness to continue cooperation with the Syrian partners in countering the terrorist threat. It once again demonstrated how fragile the situation in Syria is and stresses the necessity to continue active steps towards peace process," Moscow said in the statement.
