(Adds child killed, two others wounded, details)
MISRATA, Libya, June 20 (Reuters) - A salvo of three rockets fired by forces loyal to Muammar Gaddafi killed a child in a built-up area near the port in the rebel-held city of Misrata on Monday, a witness said. A 13-year-old child was killed in the attack on the al-Rwaisat neighbourhood, a man called Mustafa al-Gafouf, who identified himself as the child's uncle, told a Reuters reporter outside a house damaged by one of the rockets.
Two more children were wounded, he added.
A rebel at the scene called Hassan Douwa said: "Is NATO waiting for Gaddafi to kill us all before it does its job? Give us the planes and we will do it ourselves."
Another house was also damaged in the attack but no one was hurt. The third rocket exploded in an open area.
Rebels drove Gaddafi's forces out of Misrata in May after weeks of fierce fighting but their plans to advance further west toward the capital Tripoli have been slow at best.
