We demonstrate that nonlocal coupling strongly influences the dynamics of fronts connecting two
equivalent states. In two prototype models we observe a large amplification in the interaction strength
between two opposite fronts increasing front velocities several orders of magnitude. By analyzing the
spatial dynamics we prove that way beyond quantitative effects, nonlocal terms can also change the
overall qualitative picture by inducing oscillations in the front profile. This leads to a mechanism for the
formation of localized structures not present for local interactions. Finally, nonlocal coupling can induce a
steep broadening of localized structures, eventually annihilating them.
