Gasoline shortages have returned to Venezuela, sparking mile-long lines in the capital as international concerns mounted Tuesday that Iran yet again may be trying to come to the South American nation’s rescue.

Iran uses cloaking to evade detection by the United States, which seeks to block shipments to Venezuela in a campaign aimed at forcing socialist President Nicolás Maduro from power.
