Turkish President Recep Tayyip Erdogan on Wednesday stepped up his efforts to have pro-Kurdish lawmakers prosecuted, accusing them of "inciting terrorism" days after a suicide bombing in Ankara that the government blamed on Kurdish rebels.

Erdogan, who earlier this week said he wanted to expand the definition of "terrorism", urged parliament to move quickly to end immunity from prosecution for lawmakers from the pro-Kurdish Peoples' Democratic Party (HDP).

Turkish police detained eight lawyers on Wednesday as part of a crackdown on pro-Kurdish activists, their organization said, after President Recep Tayyip Erdogan said he wanted to widen the definition of "terrorism" to include academics, journalists and other opponents.

The detentions follow the arrest of three Turkish academics on Tuesday on charges of "terrorist propaganda" for signing a petition condemning military actions in operations against the outlawed Kurdistan Workers' Party (PKK).

Cyprus on Tuesday threatened to derail a proposed EU deal with Turkey to curb the flow of migrants to Europe, insisting on longstanding demands including that Ankara recognize its government.

"Cyprus does not intend to consent to the opening of any new chapters if Turkey does not fulfil its obligations," Cypriot President Nicos Anastasiades said after talks with EU president Donald Tusk.

Kurdish rebel leader Cemil Bayik warned Turkey to expect payback for the deadly clashes that have raged following the collapse of a fragile truce, in an interview published in Britain's Times daily Tuesday.

Bayik, one of the leaders of the outlawed Kurdistan Workers' Party (PKK), said to expect fighting "everywhere" and insisted its guerrillas were justified in taking any course of action.

Turkey on Monday blamed Kurdish rebels for a suicide car bombing that killed 35 people in Ankara, the latest in a series of attacks that has raised concerns about security in the country.

There has been no claim of responsibility for the Sunday evening blast, which reduced cars and buses to charred husks on a busy road in the heart of the city, wounding more than 120 people. 

Turkey's air force bombarded Kurdistan Workers Party (PKK) targets in northern Iraq this week, killing 67 rebel fighters, the military said Saturday, the first such strikes in nearly a month.

The air strikes, carried out by 14 F-16 and F-4 fighter-bombers, hit camps and other installations run by the PKK, which is designated as a terrorist organization by Turkey and its Western allies, the military said in a statement carried by local media.

Turkish prosecutors have dropped a probe into senior security officials suspected of negligence over a massive suicide bombing that killed 103 people in Ankara last year, Anatolia news agency reported Friday.

Turkey blamed the October attack, in which two bombers blew themselves up at a crowded peace rally, on Islamic State (IS) extremists acting under orders from their leadership in Syria.

Turkey's controversial draft deal with the European Union to help ease the migrant crisis will respect international law, Ankara insisted Friday, following serious criticism from the United Nations and rights groups.

EU and Turkish leaders agreed on Monday to a tentative proposal including the return of migrants landing in Greece and a 'one-for-one' swap of Syrian refugees.

A proposed EU-Turkey deal to swap Syrian refugees one-for-one will be only "temporary" and a longer-term resettlement arrangement will be necessary, the Netherlands warned Thursday.

European Union interior ministers meeting in Brussels were debating a proposal made by Ankara at a leaders' summit on Monday for a wide-ranging deal to curb the migration crisis.

Turkey's foreign minister on Wednesday rejected the idea Ankara was "begging" the EU for money, after it dramatically doubled its demand for funding during crunch talks on Europe's migrant crisis.

The European Union and Turkey clinched a deal in November for three billion euros ($3.3 billion) in funds for refugees in return for Ankara's cooperation in tackling the refugee crisis, unprecedented in the continent's history since World War II.
