The defence ministry of Russia has launched air strikes in Syria for a second day, saying that Islamic State (IS) had been targeted. The ministry said its jets had destroyed an IS ammunition depot and control centres.

However, the areas reportedly attacked appeared to be held by groups opposed to IS and the Syrian government.

The US and its allies fear the strikes have been targeting non-IS opponents of Russia's ally, Syrian President Bashar al-Assad - a claim denied by Moscow.

The latest attacks reportedly hit sites in the north-west held by the Army of Conquest rebel alliance, as well as areas in Homs and Hama provinces.

The strategic town of Jisr al-Shughour was hit, as well as areas in Idlib province and Hama province further south, according to Lebanon's al-Mayadeen TV.

Rebel activists also reported strikes at Ghantu in Homs province, close to some of Wednesday's attacks.

Russia said it had hit 12 IS positions in the past 24 hours, although this cannot be independently verified.
