Iraqi Air Force jets and tanks today attacked the Iranian border town of Mehran in the most serious incident in the feud between the two Islamic nations that erupted again last month, the official Pars news agency reported.

There was no independent confirmation of the reported border attack, which Pars said left two Iranian civilians dead, and between 30 and 40 Iranian soldiers and civilians wounded.

According to the governor general of Ilam Province, Asgher Ibrahini, the Iraqi planes bombed Iranian border posts as well as Mehran and tried to set fire to haystacks with their rockets.Ibrahini said the attack started at 7:30 a.m. and continued until 1 p.m.

The Pars account said that Iraq used three tanks in the attack and claimed that all of them were destroyed. It also said that Iran destroyed two Iraqi border posts while two of the Iranian stations were damaged.

Today's reported battle followed a similar Iraqi attack Thursday morning, in which Iran destroyed an armored personnel carrier with 20 Iraqi troops in it, Pars said.

Relations between the two neighboring countries have been deteriorating rapidly over the past year. Iranian Foreign Minister Sadegh Ghotbzadeh said today that the present government of Iraq is worse than that the deposed shah, who has been described here as being more evil than Hitler.
