Istanbul: Suspected Kurdish guerrillas detonated explosives next to a convoy carrying troops in the province of Hakkari in southeast Turkey on Thursday, wounding several people, broadcaster CNN Turk said.

It said initial information indicated an explosive device detonated by remote control caused the blast, which damaged a minibus carrying the soldiers at around 7am (0400 GMT).

The report could not immediately be confirmed.

Separatist Kurdistan Workers Party (PKK) guerrillas have stepped up their attacks on the Turkish military, killing more than 40 security personnel in the past month.

Air raids

In retaliation for those attacks, the Turkish military launched a series of air raids on PKK targets in northern Iraq last week, its first strikes in the region in more than a year.

The military has said it killed up to 100 Kurdish rebels in six days of air strikes. The PKK has said three of its fighters were killed in the strikes, while Kurdish officials say seven Iraqis were killed in an air strike on Sunday.

The increased military activity marks a return to a more hardline stance in the fight against the Kurdish guerrillas after the collapse of efforts to negotiate a settlement to the 27-year-old conflict.

The PKK took up arms against the state in 1984 and more than 40,000 people have been killed in the conflict.
