Police in Morocco have arrested 18 people in connection with a suicide bomb attack on Sunday at an internet cafe in the port city of Casablanca.
The internet cafe is not thought to be the bomber's intended target
A government spokesman said six other suspects remained at large.
Prime Minister Driss Jettou condemned the attack, which killed the bomber and injured four others, including a suspected accomplice.
"This attack will not affect Morocco's efforts towards consolidating its democratic progress," he said.
The blast occurred on Sunday evening in the district of Sidi Moumen, home to Casablanca's largest slum.
Officials said the bomber, Abdelfettah Raydi, and his suspected accomplice, Youssef Khoudri, had not targeted the internet cafe but were provoked during an argument with its owner.
The cafe's owner reportedly refused to allow the man to access to jihadist sites.
One theory is that the man was trying to access websites or email to receive instructions on where to detonate the explosives.
Several of those arrested are said to be linked to a series of co-ordinated suicide bombings in May 2003 which left 33 people dead.
