U.S.-based Muslim groups have joined governments and organizations around the world in condemning Thursday's deadly bombings in London.
In a statement, the Washington-based Council on American-Islamic Relations condemned the attacks as "barbaric crimes," which it said "can never be justified or excused."
The group has said in the past that those who commit acts of terror in the name of Islam are betraying that religion's values.
In a separate statement, the Muslim Public Affairs Council extended condolences to the families of the victims and to the British people. It called the bombings an "attack against humanity."
