Mosques and Muslim institutions across the country are having tough conversations about increased security during daily prayers after a gunman opened fire on a Muslim congregation in Christchurch, New Zealand, killing 50 worshippers and wounding dozens of others.

In Chicago, the local chapter of the Council of American-Islamic Relations urged Muslim communities to “keep vigilant” and “to take increased security precautions.”

Illinois leaders weighed in after the attack. Chicago Mayor Rahm Emanuel released a statement, saying, “An attack on any place of worship is an attack on all places of worship.”

Illinois U.S. Sen. Dick Durbin issued his own statement, saying “We must all stand together in solidarity with the Muslim community in America and in opposition to anyone who tries to divide us from our brothers and sisters of every faith.”

Morning Shift checks in with local Muslim leaders Kamran Hussain, president of the Muslim Community Center of Chicago, and Safaa Zarzour, superintendent of Universal School in Bridgeview, about how they’re approaching security for their institutions.
