Iran vowed to avenge the death of top nuclear scientist Mohsen Fakhrizadeh, who was the target of an assassination that Tehran has claimed was carried out by Israeli “mercenaries” acting on behalf of Washington.

The accusation will stoke tensions with the United States just as Donald Trump prepares to leave the White House ahead of the arrival of Joe Biden, who will have to pick up the pieces if he is to succeed in improving relations with Tehran. EFE
