Yes, in the eyes of the Catholic Church, under the guidance of the Pontifical Council for the Family abortion has been likened to murder.
The moral gravity of procured abortion is apparent in all its truth if we recognize that we are dealing with murder and, in particular, when we consider the specific elements involved. The one eliminated is a human being at the very beginning of life. No one more absolutely innocent could be imagined. In no way could this human being ever be considered an aggressor, much less an unjust aggressor!

And the notion goes even deeper and predates Christian ethics, as tied to the Hippocratic Oath.
the evident synthesis of Hippocratic ethics and Christian morality cannot be contested -both Hippocratic ethics and Christian morality regard all forms of direct abortion or direct (whether active or passive) euthanasia as illegitimate because one is dealing with an act which destroys a prenatal life and with an act of murder which nobody can justify.

So, I think in the eyes of the Church, abortion is a form of murder. In fact it is the worst possible kind of murder because it destroys the life of a completely innocent human being.
