Blast at Turkish school injures at least five children

Suspected Kurdish militants have hurled an explosive device at a middle school in the mainly-Kurdish city of Diyarbakir, injuring at least five children.

The Dogan news agency says the attack occurred in Diyarbakir's Baglar district on Friday, the last day of school when students receive report cards before a winter break.

Turkey's security forces are fighting militants linked to the Kurdistan Workers' Party, or PKK, in Diyarbakir's historic Sur district.

Authorities are enforcing a 24-hour curfew as the security forces press ahead with large-scale operations to rout out the militants.

There was no immediate information on the injured students' conditions.

The PKK has targeted schools in the past because it opposes the Turkish education system, which it says aims to assimilate Kurds.
