EU foreign ministers will meet on Monday, Jan 19, to discuss the terror threat in Europe in the wake of recent attacks, BBC News reports.

Europe is on high alert after a failed terrorist plot in Belgium and a deadly attack in Paris in which gunmen killed 17 people.

The talks will also focus on EU relations with Russia.

In Brussels, 28 foreign ministers will discuss concerns surrounding the return of radicalized Europeans who have gone to fight in Iraq and Syria.

No decisions will be taken at the meeting but a range of options will be debated in preparation for a special leaders' summit on terrorism on Feb12.

U.S. officials have confirmed that U.S. Secretary of State John Kerry will be attending talks in London about the Islamic State (IS) group.

The meeting of the members of the U.S.-led coalition against IS will take place on Thursday and will focus on "shared efforts to degrade and defeat" the militant group.

The Brussels talks come after anti-terror raids in Belgium, France and Germany led to more than 20 people being arrested. Belgium launched a series of raids last Thursday on a group of suspected jihadists. Two suspects were killed in a gun battle in the town of Verviers.

Prosecutors charged five of those arrested on Friday with "participating in the activities of a terrorist group".

Several people were also arrested in the Greek capital, Athens, on Saturday.

Belgium is asking Greece to extradite one of the suspects arrested there over a possible link with the alleged Belgian plot. Belgian police are still searching for Abdelhamid Abaaoud, the alleged leader of the cell suspected of planning to kill Belgian police officers.

No link has been established between the Belgium case and last week's attacks in France.

Gunmen in Paris killed 12 people at the offices of satirical magazine Charlie Hebdo, a policewoman and four hostages at a kosher supermarket.

The EU foreign ministers will also seek to resolve sharp differences with Russia over Ukraine.

On Sunday, heavy fighting broke out in the eastern city of Donetsk, as government forces upped operations against militants. Russian officials say President Vladimir Putin sent a letter last week to Ukrainian counterpart Petro Poroshenko with a new proposal to halt fighting in the east, but that Poroshenko had rejected it.

EU foreign policy chief Federica Mogherini said Monday's meeting would not make any new decision on sanctions.
