We report on the effect of magnetic impurities on the microscopicsuperconducting (SC) properties of the kagome-lattice superconductorLa(Ru$_{1-x}$Fe$_{x}$)$_{3}$Si$_{2}$ using muon spin relaxation/rotation(${\mu}$SR). A strong suppression of the superconducting critical temperature$T_{\rm c}$, the SC volume fraction, and the superfluid density was observed.We furthermore find a correlation between the superfluid density and $T_{\rmc}$ which is considered a hallmark feature of unconventional superconductivity.Most remarkably, measurements of the temperature-dependent magnetic penetrationdepth ${\lambda}$ reveal a change in the low-temperature behavior fromexponential saturation to a linear increase, which indicates that Fe dopingintroduces nodes in the superconducting gap structure at concentrations as lowas $x=$~0.015. Our results point to a rare example of unconventionalsuperconductivity in the correlated kagome lattice and accessible tunability ofthe superconducting gap structure, offering new insights into the microscopicmechanisms involved in superconducting order.
