The Saudi Arabia-led coalition of Arab nations has dismissed Iran's allegations that it' warplanes attacked an Iranian diplomatic mission in Sana'a.

"The coalition command confirmed that these [Iranian] allegations are false and void, stressing that it does not carry out any operations in the vicinity of the embassy or near it," the grouping said in a statement released on state-run Saudi Press Agency Thursday, according to Reuters.

Iran earlier accused Saudi Arabia of attacking its embassy in Yemen's capital city.

"This deliberate action by Saudi Arabia is a violation of all international conventions that protect diplomatic missions. The Saudi government is responsible for the damage caused and for the situation of members of staff who were injured," an Iranian foreign ministry official told state television, according to AFP.

Saudi Arabia severed its diplomatic ties with Iran on Sunday after a group of protestors stormed its embassy in Tehran following the execution of al-Nimr, as HNGN previously reported.

Iranian President Hassan Rouhani responded by saying that Saudi Arabia cannot hide its "great crime" of beheading the cleric by cutting diplomatic ties with Tehran.

"The Saudi government, in order to cover up its crime of beheading a religious leader has resorted to a strange measure and has severed its ties with the Islamic Republic, whereas, undoubtedly, such moves will never hide that great crime," Rouhani said Tuesday, according to state-run Press TV.

Saudi Arabia executed the cleric and 46 others last week. They were convicted of plotting and carrying out serial bomb blasts in the kingdom.
