SULAYMANIYAH (Reuters) – A Katyusha rocket targeted employee housing UAE energy firm Dana Gas in Sulaymaniyah in northern Iraq on Friday, landing in the company’s Khor Mor gas field, two security sources said. Friday’s attack was the second on Dana Gas facilities this week. A Katyusha rocket landed inside Khor Mor on Wednesday but caused no damage, Sulaymaniyah’s counter-terrorism service said. Local television broadcasts on Friday showed a column of rising smoke near the field with sirens sounding. No group has claimed responsibility for either attack.
