Avigdor Lieberman, the head of Israel's foreign and defense committee, on Tuesday called for tougher sanctions against Iran to curb its nuclear drive, saying the current measures were not enough.

Speaking as world powers were holding talks with Iran over its disputed nuclear program, the former foreign minister said Israel had "no illusions on Iran's intention of dragging out the process and wasting time".

"Based on the experience with North Korea, the international powers must realize that sanctions alone will not suffice," Lieberman said in remarks relayed by the parliamentary committee's spokesman.

"In order to rein them in, it's time to resort to more practical measures," he said without indicating their nature or source.
