Turkey's Bursa city targeted in suicide attack
The blast occurred near the city's 14th century Grand Mosque.
No group has yet claimed the attack, but Turkish officials told Reuters that the culprit was female.
The attack is the latest of several that have rocked Turkey in recent months.
Earlier this month, two soldiers were killed and dozens were wounded in a car bomb attack that targeted a military post in Turkey's restive Kurdish-dominated southeast.
Turkish authorities blamed the attack on the outlawed Kurdistan Workers' Party (PKK), which has killed hundreds of members of the security forces in a resurgent campaign in the past few months, as Ankara cracked down on Kurdish areas with a renewed military campaign.
The Islamic State group has also played a part in Turkey’s deteriorating security crisis, with several attacks being conducted in Istanbul.
In March, a suicide bomber struck a popular shopping street in the heart of Istanbul - killing four people and injuring dozens - in an attack which authorities blamed on the Islamic State group.
Turkey's latest trend has forced numerous governments to issue travel alerts in a bid to prevent citizens from visiting the country.
The United States warned its citizens about "credible threats" to tourist areas in Turkey, especially around public squares and docks in Istanbul and the Mediterranean city of Antalya following the previous attacks.
