"The Israeli government expresses its shock and strongly condemns the terrorist attack in the city of Turku last Friday in which two people were killed and eight wounded", it said in a statement released Monday.
Detectives said he came to Finland as an asylum seeker in 2016.
Police will also request the detention of four other Moroccan citizens who were arrested in an overnight raid on a Turku apartment building and refugee housing centre just hours after the attack.
The attack happened in the Puutori/Market Square area of Turku just after 4pm local time, with police receiving reports of a man attacking passers-by with a knife.
According to the Yle broadcaster, a foreign national had contacted the Southwest Finland Police Department early in 2017 about the suspected perpetrator of the attacks, claiming that he was radicalized and interested in extreme ideology. An Italian, a Swede and a Briton were among the injured.
