DAMASCUS (AP) — President Bashar Assad rejected claims that Syria's alliance with Iran had been weakened by Damascus' participation in last month's U.S.-sponsored Mideast peace conference, insisting Thursday that ties between the two countries will never be shaken.

Assad made the comments as he inaugurated two joint Syrian-Iranian industrial projects — factories for cars and cement, according to the official SANA news agency. He was joined at the ceremonies by the Iranian industry and housing ministers.
""Inaugurating this plant in partnership with our Iranian brothers and officials is a response to those who tried to circulate (reports) ... that relations between the two countries have been shaken,"" SANA quoted Assad as saying.
""I confirm, on this occasion, that relations will not be shaken for any reason or under any circumstance,"" Assad said at the factory in Hasya, some 100 miles north of the capital Damascus.
Syria is Iran's closest Arab ally. The two countries have had warm relations since 1980 when Syria sided with Iran against Iraq in the 1980-88 Iran-Iraq war.
