British Prime Minister David Cameron has slammed Russia’s airstrikes against the ISIL terrorists in Syria, arguing they would make “the situation worse.”

“"It's absolutely clear that Russia is not discriminating between ISIL and the legitimate Syrian opposition groups and, as a result, they are actually backing the butcher Assad and helping him," Cameron was quoted by the British media as saying on Saturday.

"Rightly, they [Russia] have been condemned across the Arab world for what they have done and I think the Arab world is right about that…But we should be using this moment now to try to force forward a comprehensive plan to bring political transition in Syria because that is the answer for bringing peace to the region,"  he added.

Campaign against terrorists

Russia’s Air Force has carried out more than 60 flights in Syria in the past 72 hours, said a senior Russian army official on Saturday.

Andrei Kartapolov from the Russian army's General Staff also emphasized that the military potential of terrorists has been significantly reduced as a results of the airstrikes.

Russia's Air Force targeted more than 50 Islamic State objects in the air strikes, he noted.

"The strikes were carried out around the clock from the Hmeymim air base along the whole depth of the territory of Syria," Kartapolov was quoted as saying by RIA news agency.

The Kremlin has announced that the air strike campaign against the ISIL terrorists will last three to four months.

"There is always a risk of being bogged down but in Moscow, we are talking about an operation of three to four months," Alexei Pushkov, the head of the lower house of the Russian parliament's foreign affairs committee said on Friday.

Criticizing Russia

The United States, alongside its Western and regional allies, has already expressed serious concerns over Russia’s military airstrikes in Syria which are carried out at the request of the Syrian government.

They claim that the airstrikes are not precise enough and target the foreign-backed militants who are fighting against the Syrian government.

Moscow has rejected the allegations and emphasized that ISIL positions inside Syria are the main targets of the air raids.

'Sabotaging' US-led plans 

A London-based political expert believes that the US and its allies are angry about Russia’s air strike campaign in Syria as it disturbs their plans “to stay in the region for a long time.”

“They basically do not want Russia to gain ground in the Middle East at all. They basically want to dominate the entire Middle East. They have an alliance which they call the anti-ISIL alliance which has a long-term plan that is going to last according to what they say from three to five years and even longer. They are basically planning to stay in the region for a long time," Zayd al-Isa told Press TV’s UK Desk on Saturday.

"Now for the Russians to come and start bombing ISIL and other terrorists groups, they think that will shorten the life of ISIL and will in a way sabotage their plans for actually staying in the region for a long time," he reiterated.
