German authorities say a woman has died from injuries sustained in a suicide bombing last month in Istanbul, bringing the number of people killed in the attack to 12.

Bavaria's state interior ministry said Tuesday that the 52-year-old woman died on Sunday at a hospital in Offenbach, near Frankfurt, news agency dpa reported.

The bomber set off the explosion on Jan. 12 near German tourists visiting Istanbul's landmark Blue Mosque, killing 10 of them. An 11th victim died in Berlin in late January.

Turkish officials have said the bomber, a Syrian, was affiliated with the Islamic State group.
