Kabul, Afghanistan (CNN) -- Afghanistan's election commission says violence against candidates and their supporters for next month's parliamentary polls is increasing.
Three candidates and 13 candidate supporters have been killed and 15 people from various candidate campaign teams have been injured.
"Regretfully, we are being informed on daily basis that security threats have increased," Afghanistan's Independent Election Commission said in a news release. "The commission strongly condemns these cowardly acts, and has prayed for their departed souls."
On September 18, 249 seats in the Wolesi Jirga, or House of the People, are at stake.
The IEC said it expects from all security forces to take the proper action against people who assault candidates.
The agency said it "considers the elections as the means to transfer leadership in a peaceful manner for the political future of the people" and it "is constantly urging the insurgents and anti-government elements to stop the war, and pursue their ambitions through the will and support of the people in the elections."
