A suicide bombing inside a Shia mosque north of the Iraqi capital Baghdad during evening prayers there left at least 14 people dead, media reported Sunday, June 23, according to RIA Novosti.

Twenty-five people were injured in the attack that occurred Saturday in the Sab al-Bor district, Al Jazeera quoted sources as saying. The attack was made after other attacks on the same day killed at least nine people north of the city.

The blasts are the latest instances of violence in Iraq, prompting fears of a return to full-scale sectarian war, the Qatar-based broadcaster reported.

Iraq has seen a surge in violence since the year start. Over 1,000 people were killed in the country in May.
