We prove and generalize several recent conjectures of Z.-W. Sun surrounding binomial coefficients and harmonic numbers. We show that Sun's series and their analogs can be represented as cyclotomic multiple zeta values of levels N E {4, 8,12,16, 24}, namely Goncharov's multiple polylogarithms evaluated at N-th roots of unity.
