A mixture of signals including Scud missiles, smiles and something of the old revolutionary stance is coming out of Iran and confusing its Arab neighbours in the Persian Gulf.
Following overtures from President Mohammed Khatami, regarded by the outside world as the most moderate of Iran's post-revolution leaders, a new campaign of tough diplomacy is confusing observers and causing a split among Arabs.
Just two weeks after President Khatami's fence-mending tour in the Arab world, where he visited Syria, Saudi Arabia and Qatar, Iran fired Scud missiles at a base north of Baghdad. The base is the headquarters of the Iranian exiled group Mujahedi-e-Khalq. Bombs, believed to have been planted by Iranian agents, exploded in other bases of the Iranian opposition group, generating protests from Iraq.

It also indicates that Iran remains deeply opposed to reconciliation with Iraq, its foe in an eight-year war during the 1980s and its principal historic rival.
Despite a warm reception in Jeddah in May, where President Khatami held talks with Crown Prince Abdullah, Arabs have been warning that the differences with Iran are of an historic nature.
Mr Khatami's tour was his first foray into the Arab world and part of an attempt to ease his country out of years of isolation and external tensions. His visit to Saudi Arabia was the first by any Iranian leader since the 1979 Islamic revolution. While using his mild manner and...
