Germany's Westerwelle urges tougher EU sanctions on Iran

Germany's foreign minister is urging the EU to adopt even tougher sanctions against Iran to hinder the country from building nuclear weapons, Associated Press reports.

Guido Westerwelle said on Sunday "we must increase the pressure through sanctions" because Iran has failed to make any concessions during talks on its nuclear program over the past months.

His comments came a day before a meeting of European foreign ministers in Luxembourg at which further sanctions will be discussed.
