Minister resignation

 

Sectarian violence has remained at ferocious levels despite a US-Iraqi security sweep that is in its seventh week.

 

Amid the attacks, Hashim al-Shibli told Al Jazeera on Saturday that he had tendered his resignation from the post of justice minister after differences in political and economic policy in cabinet became insurmountable.

Al-Shibli was elected to government in December 2005 as part of the secular coalition, the Iraqi National List.

 

He told the Associated Press that he would continue to act as justice minister while awaiting the cabinet's response.

 

Al-Shibli has been involved in a dispute over the cabinet's recent endorsement of a decision to relocate and compensate thousands of Arabs who moved to Kirkuk, a northern Iraqi city with large oil reserves, during an "Arabisation" campaign in the 1980s.

 

The Iraqi National List and several Sunni legislators have objected to the decision, saying it fails to address key issues, including property claims.

The interior ministry said the number of wounded was 347.
