Hours after the assassination, an axe-wielding Palestinian wounded three people outside an army base near Tel Aviv on Monday.
There was no immediate claim of responsibility for the attack, which followed vows of revenge by Hamas and another resistance group, al-Aqsa Martyrs Brigades, for the killing of Yasin in a helicopter missile strike in Gaza.
"A man from the Palestinian territories got out of a car and attacked three people with an axe," a police officer told Israel Radio.
A police statement said two men and a woman were injured, none seriously, in the incident outside the army base in the city of Ramat Gan and that the Palestinian was arrested.
Also on Monday, a loud explosion echoed on the Palestinian side of the main crossing between Israel and the Gaza Strip and an Israeli soldier said a bomb was thought to have detonated there.
"A small bomb exploded on the Palestinian side," an Israeli
soldier manning a watchpost told Reuters.
But Palestinian security sources said the blast was believed to have been caused by a makeshift Qassam rocket fired by Hamas fighters in the aftermath of Yasin's killing.

Israeli military sources said they had no details about any possible casualties.
Qassam rockets, named after Hamas' military wing, are frequently fired by Hamas, but have never led to any Israeli fatalities.
A 13-year-old Palestinian boy was killed by Israeli troops during a mass demonstration in the southern Gaza Strip town of Khan Yunis in support of the slain Yasin.
Medics named him as Musab al-Khalban and said he had been fatally hit in the head when troops opened fire from a watchtower in the nearby Jewish settlement of Ganei Tal.
They said four other people were moderately wounded during the demonstration.
