Foreign Minister Avigdor Lieberman on Thursday promised to strengthen ties with Belarus, but cautioned the ex-Soviet nation against developing relations with Iran. After talks with Belarusian officials, Lieberman said that Iran is a threat to stability in the entire Middle East, and that Israel expects them to take its concerns into account. Belarus' authoritarian President Alexander Lukashenko has developed close ties with Iran, calling the Islamic republic a "key partner." He and Iranian President Mahmoud Ahmadinejad have exchanged visits and warm words of solidarity. Russia has been Belarus' main sponsor, but Lukashenko recently has sought to improve Belarus' ties with the West.
