BAGHDAD (Reuters) - Iraq's most influential Shi'ite cleric urged political leaders on Friday to refrain from clinging to their posts - an apparent reference to Prime Minister Nuri al-Maliki, who has defied demands that he step aside. Speaking through an aide who delivered a sermon after Friday prayers in the holy city of Kerbala, Grand Ayatollah Ali al-Sistani said leaders should show flexibility so that political deadlocks could be broken and Iraq could confront an insurgency.
Maliki has come under mounting pressure since Sunni militants led by the hardline Islamic State swept across northern Iraq last month and seized vast swathes of territory, posing the biggest challenge to Maliki's Shi'ite-led government since U.S. forces withdrew in 2011.
