We confirm two new luminous LAEs at $z=5.676$ (SR6) and $z=6.532$ (VR7), and also present {\\it HST} follow-up of both sources. These sources have luminosities L$_{\\rm Ly\\alpha} \\approx 3\\times10^{43}$ erg s$^{-1}$, very high rest-frame equivalent widths of EW$_0\\gtrsim 200$ {\\AA} and narrow Ly$\\alpha$ lines (200-340 km s$^{-1}$).
