The imam of Brussel’s Grand Mosque says that Muslim condemnation of the recent terrorist attacks in the city “is not enough anymore.”

Galaye Ndiaye believes much more needs to be done to discourage young people from becoming radicalised. It’s estimated that 500 young people from Belgium have gone to fight in Iraq and Syria.

On Thursday, leaders at the Grand Mosque draped the Belgian national flag and European Union flag outside the mosque, determined to send out a clear message that they too are angry and grieving over the recent attacks.

“We have to go up a gear” Ndiaye told Euronews, “that’s why we have started with this symbolic event but there will also be a programme about radicalisation and religious fanaticism here at the Islamic centre.”

Muslims arriving at the mosque supported the message.

“I was very concerned about the events of tuesday” said one woman, “I was on public transport myself when it happened. As a Muslim it has touched me even more, as I know that we’re always under suspicion.”

Another woman said: “those who have done this are not Muslims, because Islam is a religion of peace and love. It has nothing to do with what those people have done.”

On Friday, more than two thousand Muslims are expected to gather outside the Grand Mosque in Brussels just before midday prayers to show their solidarity and to condemn Tuesday’s bomb attacks which killed more than 30 people and injured hundreds more.
