ISTANBUL (Reuters) - A small bomb exploded in front of military housing in the southeastern Turkish city of Diyarbakir overnight, wounding two people slightly, state-run Anatolian news agency reported on Friday.
On Thursday, a bomb on a bicycle wounded seven people including a police officer in Istanbul in what Prime Minister Tayyip Erdogan said bore the marks of the main Kurdish militant organization.
Nobody has claimed responsibility for the blasts, which came ahead of a parliamentary election on June 12.
Anatolian described the device used in Diyarbakir as a percussion bomb, which generally makes a loud noise but causes limited damage. It was thrown at the military housing by an unidentified assailant.
Turkish security forces are on alert due to growing militant activity in recent weeks, including attacks on police.
Kurdistan Workers Party (PKK) guerrillas have been fighting Turkish security forces since 1984 in a separatist insurgency which has killed more than 40,000 people.
Erdogan's AK Party is expected to secure a comfortable victory next month to win a third consecutive term in office, having first come to power in 2002.
