"We reject any call for a change of the government by non-democratic and non-constitutional means," he said at an Iftar, the meal which breaks the fasting day during the holy month of Ramadan, in his Koreitem mansion Tuesday.

The Iftar, that was attended by Siniora, other high-ranking politicians and diplomats, was made in the premier's honor.

Hariri also insisted on respect for national agreements calling for the disarming of all militias in Lebanon. It was a clear reminder to the Syrian and Iranian-backed Hezbollah, the only group that was not disarmed at the end of the country's devastating 1975-1990 civil war.

"We declare that the Taef agreement will stay," Hariri said, reiterating his full-fledged willingness for dialogue based on the accord that ended the Lebanese civil war.

An Nahar newspaper quoted a member of the parliamentary majority as saying on Wednesday that Hariri's "strong and clear" message represented a comprehensive retort of the anti-Syrian March 14 forces to Sayyed Hassan Nasrallah's demands.

He described Nasrallah's address to his supporters at Friday's "Divine Victory" rally as "unacceptable local translation of (Syrian President) Bashar Assad's speech."

At the rally, Nasrallah called for a national unity government. He also said his group had increased its arsenal to more than 20,000 rockets and would not disarm as long as the Lebanese government was not strong enough to face danger from Israel.

Hariri, noting that the Israeli devastating offensive left 1,200 civilians killed in Lebanon, said "the Israeli aggression plunged Lebanon into deep catastrophe, as the enemy is now occupying more territory, is holding more prisoners."

"While a big crime was committed by (Israeli Prime Minister Ehud) Olmert, some want to hold Siniora accountable," he said.

Hariri's speech on Tuesday came a few days after other members of the March 14 alliance insisted that allegiance to Damascus would not achieve national unity.

Lebanese Forces leader Samir Geagea said Sunday that before demanding a national unity government Hezbollah must work to achieve national unity.

"They can not take pride in relations with Syria and at the same time claim allegiance to Lebanon," he said

MP Walid Jumblat, PSP chief, another fiery anti-Syrian critic, also said that as long as Nasrallah is pledging allegiance to the Assad regime in Damascus, the March 14 forces will not come to an agreement with him.
