Iran's parliament has controversely approved the nomination of Ahmad Vahidi, who is accused of involvement in a 1994 bomb attack in Argentina, as defence minister. Argentine officials have said Vahidi is "deeply implicated" in the attack on a Jewish cultural centre in Buenos Aires in which 85 people were killed. Argentina has condemned his nomination as "an affront to the victims" of the bombing and has formally accused Iran of masterminding it, which Tehran has denied.
