A hand grenade exploded on a busy street in Istanbul on Sunday without causing any casualties, state media said, almost two weeks after a suicide bombing in Turkey's largest city.
The megacity remains on high security alert following the attack by a female suicide bomber on January 6 in the heart of Istanbul's tourist district that killed a Turkish policeman.
A large number of police in armoured vehicles sealed off the area after the grenade exploded Sunday in the conservative and densely populated Fatih district, the official Anatolia news agency reported.
In other security alerts on Sunday, two unexploded bombs were found in different parts of Istanbul, Anatolia said.
Police detonated a cluster bomb found outside a police station in the suburb of Maltepe on the Asian side of Istanbul.
The package included a note that read "Cizre will be avenged" -- an apparent reference to the alleged killing by police of a 12-year-old boy Wednesday in the largely Kurdish southeastern town of Cizre.
Police also defused a bomb in a suspicious package left by two masked men at a bus stop in the suburb of Sultanbeyli after witnesses raised the alarm.
The initials of the Patriotic Revolutionary Youth Movement (YDG-H), a youth branch of Turkey's outlawed Kurdistan Workers' Party (PKK), were written on the package.
Security has been high in Turkey over the past few months amid fears of attacks by Kurdish militants and jihadists controlling parts of Iraq and Syria up to the Turkish border.
Turkey has arrested six people over the suicide bombing in Istanbul's Sultanahmet district, home to the city's greatest concentration of historical monuments.
Turkish authorities have so far refrained from naming the bomber but reports Friday identified her as Diana Ramazanova, 18, from the northern Caucasus region of Dagestan.
She was said to have been the widow of a Norwegian jihadist who died fighting for the Islamic State group in Syria.
