Let G be a semi-simple simply connected algebraic group over the field C of complex numbers. Let T be a maximal torus of G, and let W be the Weyl group of G with respect to T. Let Z(w, (c) under bar) be the Bott-samelson-Demazure-Hansen variety corresponding to a tuple (i) under bar associated to a reduced expression of an element w is an element of W. We prove that for the tuple (i) under bar associated to any reduced expression of a minuscule Weyl group element w, the anti-canonical line bundle on Z(w, (i) under bar) is globally generated. As consequence, we prove that Z(w, (i) under bar) is weak Fano. Assume that G is a simple algebraic group whose type is different from A(2). Let s = {alpha(1),..., alpha(n)} be the set of simple roots. Let w be such that support of w is equal to s. We prove that Z(w, (i) under bar) is Fano for the tuple (i) under bar associated to any reduced expression of w if and only if w is a Coxeter element and w(-1) (sigma(n)(t=1) alpha(t)) is an element of- s.
