The anniversary of terrorist Abu Jihad's death is a "prominent national event" in April

“It is not surprising that it is raining and snowing in April, especially since our fathers told us in their proverbs that the rains of April revive the man and renew the hope after a long wait and forgetfulness. It is known that in April, from a Palestinian point a view, there are many national events, the most prominent are perhaps Children’s Day, Prisoners’ Day, the anniversary of leader Abu Jihad Al-Wazir’s Martyrdom death, as well as the anniversary of the Martyrdom death of the two Kamals (i.e. Kamal Adwan and Kamal Nasser) [and the anniversary of the deaths of] Martyr Abd Al-Aziz Al-Rantisi and a long list of Martyrs.”
