The euro zone's annual inflation rate is expected at 0.5 percent in June, stable compared with May, said Eurostat, the statistical office of the EU, on Thursday.

Looking at the main components of inflation in June, tobacco is expected to see the highest annual growth, followed by restaurants and cafes, and rents.

In the 28-member EU, annual inflation was 0.7 percent in June, up from 0.6 percent in May, said Eurostat.

Compared with May, annual inflation fell in 10 EU member states, remained stable in four, and rose in 14.

The figure was well below the 2-percent target set by the European Central Bank (ECB).

ECB President Mario Draghi said Monday that the bank was open to additional aggressive stimulus measures if they are needed to keep inflation from staying too low for too long.

His remarks came after the International Monetary Fund renewed its call for the ECB to consider big asset purchases to revive lending in the euro zone and keep ultra-low inflation from damaging the bloc's recovery.
