A message is written on the ground as people leave tributes at the Place de la Bourse following today's attacks on March 22, 2016 in Brussels, Belgium | Carl Court/Getty Images Belgian Muslims condemn attacks, donate blood Some Muslim leaders voiced concern over possible repercussions and racism against their community.

Leading Belgian and European Muslim groups condemned Tuesday's attacks in Brussels.

"These were barbaric acts," said Said Kamli, the director of the Federation of Islamic Organisations in Europe, adding that the Islamic State of Iraq and the Levant (ISIL) and its terrorist activities do not represent Islam. "We do not support people who do these things. We hope they face justice."

ISIL claimed responsibility for the attacks that killed 31 and wounded more than 170.

Some Muslim leaders voiced concern over possible repercussions and racism against their community in the wake of the attacks.

"It's catastrophic for Muslims," said Ezzedine, who works at the Islamic Cultural Center of Belgium and asked that only his first name be used.

"No one here is okay with [the attacks.] We only want to pray, not condone terrorism," said Mustafa, a member of the Ulu Camii mosque in Brussels, who also only wanted to give his first name.

Community members made a point of showing their solidarity with victims, joining the throng of Belgians looking to give blood to the wounded.

Groups of Muslim women arrived at St. Pierre Hospital in Brussels throughout the morning, ready to donate.

Many of them were turned away after the hospital said their stocks were already full.
