KABUL: Seven Afghan Army officers, including two generals, have been sacked over a deadly attack on a Kabul military base, President Ashraf Ghani said Tuesday, as the Afghan capital braces for further assaults.At least five attackers ? gunmen and suicide bombers ? launched the pre-dawn raid claimed by the Islamic State group on January 29, killing 11 soldiers and wounding 16. ?Seven high-ranking officers including two generals committed professional negligence. All seven are sacked and referred for further investigations,? Ghani said on Twitter after a probe into the incident. Ghani?s US-backed government is under growing public pressure to improve security in the capital after a series of attacks demonstrated the ability of the Taliban and Islamic State group to strike at the heart of the country.
