The Jordan Armed Forces on Tuesday said a multinational military drill that started in Jordan this week does not include using chemical weapons, the state-run Petra news agency reported. The Jordan-hosted "Eager Lion" international military drill with the participation of 22 countries seeks to strengthen the skills of the Jordanian army and enhance cooperation, the army said. More than 13,000 army personnel are taking part in the drill, which lasts until June 10. The army said holding the military drill does mot have any relation to the developments in the region. The drill will focus on unconventional warfare that could undermine security, such as terrorism, insurgency and border breaches. The exercise focuses on wide range offensive and defensive operations, while including disaster relief, strategic communication and rescue operations.
