Turkish warplanes bombed Kurdish militant targets in northern Iraq Monday, as Ankara pressed its military operation against Islamic State jihadists and a Syrian Kurdish militia in neighbouring Syria, state media said.

Turkish air force jets launched strikes between 09:30 and 10:55 GMT against targets of the "separatist terrorist organisation" in Gara in northern Iraq, Anadolu news agency said, referring to the outlawed Kurdistan Workers' Party (PKK).

The targets were "destroyed", Anadolu added.

The PKK is proscribed as a terrorist organisation by Turkey, the European Union and the United States and its command is based in the Qandil mountains of northern Iraq.

A two-year ceasefire between Ankara and the PKK collapsed last year, after which Kurdish rebels launched frequent attacks on security forces in the restive southeast.

Since Wednesday, Turkey has been conducting an operation in Syria against IS and the Syrian Kurdish People's Protection Units (YPG).

The air strikes in northern Iraq were the first since the Syria operation began on Wednesday.

Turkey describes the YPG as a "terrorist organisation" and an offshoot of the PKK. With US air support, the group has successfully fought against IS, taking territory from the group in north Syria.

IS-claimed attack kills 18 in Iraq oasis town
Karbala, Iraq (AFP) Aug 29, 2016 - Attackers armed with suicide vests, rifles and grenades killed 18 people in the Iraqi oasis town of Ain al-Tamer, many of them guests at a wedding party, officials said Monday.

The attack, a rare occurrence in this region southwest of Baghdad, was claimed by the Islamic State (IS) jihadist group.

"They were carrying Kalashnikovs, hand grenades. One of them blew himself up and the others were killed by the security forces," said the head of central Euphrates operations command, Qais Khalaf.

A local council member and a provincial health directorate source confirmed the death toll in the attack, which took place late Sunday, and said at least 26 others were wounded.

Ain al-Tamer is located 50 kilometres (30 miles) from the Shiite holy city of Karbala and on the edge of Anbar province, long a haven for jihadists.

IS said in a statement posted on social media that its men, all of them Iraqis, fought the security forces for several hours before detonating their suicide vests.

Officials said the attackers started opening fire in a neighbourhood of Ain al-Tamer at around 1830 GMT on Sunday, although it was not immediately what their target was.

Five members of one family were among the dead, according to a health official from Karbala province.

"The five terrorists were carrying lots of weapons and one of them blew himself up in the midst of our citizens," said Farhan Jassem Mohammed of the local council.

"Some of them were wearing civilian clothes, others military clothes. They infiltrated from the west under the cover of darkness," he said.

"One of them may have managed to flee. There is an ongoing search," Mohammed told AFP.

- Wedding party -

The IS statement mentioned only four attackers.

A former mayor of Ain al-Tamer told AFP the attackers started spraying bullets at a nearby wedding party.

"The attack kicked off as people were attending a wedding party in the neighbourhood. Several among the dead and wounded were at the party," said Mahfouz al-Tamimi, who is now a Karbala provincial council member.

Military commanders said the attackers came from the Anbar desert to the west, a region that is overwhelmingly Sunni and borders Saudi Arabia, Jordan and Syria.

Iraq's security forces have for months been battling IS fighters in Anbar, notching up key victories in provincial Ramadi and jihadist bastion Fallujah earlier this year.

IS recently lost control of an area in Anbar called Jazirat al-Khaldiyeh, a key crossroads that jihadists used to move fighters and supplies between fronts since they seized large parts of Iraq in 2014.

The attack on Ain al-Tamer, in which guerrilla fighters doubled up as suicide bombers, bore the hallmark of IS.

The jihadists call such operations "inghamasi" -- which literally means "plunging" and refers to the act of penetrating deep into enemy territory.
