Solana made the promise in a joint news conference in Jerusalem with Israeli Foreign Minister Tzipi Livni.

"We will try to continue working with all the friends in the (Middle East) region to stop as soon as possible" the bloodshed and the suffering which is taking place now, Solana told the reporters.

He, meanwhile, condemned Lebanese Hizbollah's cross-border raid on July 12 that led to the ongoing Israeli offensive in Lebanon, urging the group to release the two Israeli soldiers it held.

Solana, who arrived in Israel after meeting with top Lebanese officials in Beirut to work for a diplomatic solution to the crisis, also implicitly called on Syria and Iran, which "may have influence" to Hizbollah, to help end the ongoing conflict.

Livni, for her part, reiterated Israel's demands for a truce including an unconditional release of the soldiers, disarmament of Hizbollah and its removal from south Lebanon, so that the Lebanese government "can assert its control over all of Lebanon."

"Israel and the international community have the common goal toinitiate a move that will bring a long-term change in the region and prevent the terror that Israelis and Lebanese are facing," shesaid.

Solana earlier met with Israeli Prime Minister Ehud Olmert and was due to meet Palestinian President Mahmoud Abbas Wednesday evening.
