The funeral began with a traditional Friday prayer at the Islamic Society in Denmark mosque, which usually holds around 650 people, according to the local BT newspaper.
The mosque was reportedly packed to capacity and several people joined in from the courtyard, where carpets had been rolled out on the ground.
“I knew Omar, we lived in the same place. But he is not as he has been portrayed in the press. He was a good guy. He was not a terrorist, but a poor guy who lacked help,” one of the attendees told BT.
Police were present both at the mosque and at the burial site, but the officers remained at a distance, the newspaper said.
Hours later, a man standing guard outside a synagogue in the Danish capital was fatally shot. Several police officers were wounded in the shootings.
El-Hussein, suspected of carrying out both attacks, was killed by police early Sunday. According to local authorities, the 22-year-old had a criminal record and was released from prison just two weeks ahead of the attacks
