BRATISLAVA, Slovakia (AP) — Slovaks are planning a national rally to honor an investigative journalist shot dead last week along with his partner.

The organizers said that 25 marches are planned Friday in Slovakia, including in the capital, Bratislava, at which President Andrej Kiska will attend.

Other commemorative gatherings are planned in two dozen cities abroad, including London, Paris and Brussels.

The bodies of 27-year-old Jan Kuciak and his girlfriend, Martina Kusnirova, were found Sunday in their house.

Kuciak's last, unfinished story was about the activities of Italian mafia in eastern Slovakia and their ties to people close to Prime Minister Robert Fico.

The rallies are taking place amid calls for international experts to join the investigation and for Interior Minister Robert Kalinak, who was linked to corruption scandals in the past, to resign.
