The return of “Islamist terrorism” is a threat for all European nations, French President Emmanuel Macron said during a visit to Albania on Tuesday.

“Unfortunately we saw it yesterday in Brussels: all European states are vulnerable. And, in fact, there is a return of this Islamist terrorism, and we are all unprotected,” Macron said, referring to an attack in which two Swedish soccer fans were killed in the Belgian capital, Brussels.

The suspected killer, a 45-year-old Tunisian man, died on Tuesday after being shot by police in a cafe, informed the Belgian authorities.

Macron, during a media conference in Tirana, said intensive talks were also underway to release hostages held by Hamas after its attack on Israel, and after a mother of a French-Israeli hostage pleaded with world leaders to intervene.

“I want to be very careful here … so that we don’t jeopardize the intensive talks that we are currently having,” Macron told reporters in the Albanian capital, Tirana.

“But they are progressing and we are following these talks hour by hour.”

The mother of Mia Shem, a French-Israel girl held hostage by Hamas militants in Gaza, called on world leaders on Tuesday to free her daughter after the militants released a video showing her being held captive.

“I ask world leaders that my daughter be returned to us in the condition she is in today, as well as the other hostages,” Keren Shem said at a press conference in Tel Aviv.

She was speaking a day after Hamas released a video showing her daughter being treated for a chest wound.
