An Iraqi Kurdish rebel faction says a Turkish air raid on northern Iraq on Thursday killed at least nine Iraqi Kurds, among them seven civilians.
Turkish troops crossed into northern Iraq two weeks ago to wipe out rebel bases used to launch attacks on Turkey.
On Thursday, several hundreds demonstrators took to the streets of Baghdad to condemn the Turkish incursion of Iraq.
Some 600 demonstrators gathered in front of the Turkish Embassy in Baghdad to protest the ongoing Turkish invasion of Northern Iraq.
Turkey's two-week military sweep has so far killed some 18-hundred Kurdish rebels.
Carrying banners with anti-Turkish slogans and placards of Iraqi leader Saddam Hussein, many demonstrators shouted "Turkey is against the Arabs ... close their embassy" and "Down, down with Turkey and Israel".
Some protesters demanded that Iraq drive the Turkish troops out by force, while others called for a boycott of Turkish goods.
Among the protesters were a number of different nationalities, such as Yemenites, Jordanians, Sudanese, Palestinians and Iraqis.
The protestors handed a petition to Turkish officials.
"We demanded an immediate withdrawal of Turkish forces from Iraqi land. Turkey's action is an act of violation to international law."

The demonstrators also included a group of Kurds demanding the return of the region to Baghdad authority.
"In the name of the Revolutionary Party of Kurdistan, member of Iraq's progressive national front, the real representative of the Kurdish people, we say that the Turkish invasion of the Iraqi lands is a violation of international law and the UN charter so we demand an immediate withdrawal of Turkish forces from Iraqi land, that the forces go back to Turkey because Kurdistan is a dear part of great Iraq."

Also Thursday, a group of demonstrators gathered in front of the United Nations offices in central Baghdad to protest what it considered to be the world body's inaction.
The Kurds, who have been fighting for autonomy in south-eastern Turkey since 1984, had set up bases in northern Iraq to stage raids into Turkey.
Iraq has condemned the Turkish incursion in the north, home to its own Kurdish population. Its anger comes at a time when there is widespread concern in the Arab world over Ankara's recent moves to forge closer military ties with Israel.
Iraq's Kurdish factions are in charge of a de-facto Kurdish state established after the 1991 Gulf War under Western protection.
An intervention in the area last year by Iraq's army in support of one Kurdish faction against another triggered U-S missile attacks against Iraq.
