Palestinian Prime Minister Salam Fayyad harshly condemned the bombing in Jerusalem on Wednesday that killed one person and wounded at least 30 others in Jerusalem, calling it a "terror attack".

"Even though we do not have enough information regarding the attack, I harshly condemn this act of terror regardless of who is behind it," said Fayyad, wishing a quick recovery to all those wounded from the bombing.

Fayyad also stressed that these actions completely contradict the Palestinian people's plan to "achieve freedom by peaceful means."

Palestinian President Mahmoud Abbas, traveling in Russia, issued a similar statement condemning the attack.

U.S. President Barack Obama on Wednesday condemned the Jerusalem bombing as well as rockets and mortars fired from Gaza in recent days.

"I condemn in the strongest possible terms the bombing in Jerusalem today, as well as the rockets and mortars fired from Gaza in recent days. Together with the American people, I offer my deepest condolences for those injured or killed," Obama said in a written statement.

"There is never any possible justification for terrorism. The United States calls on the groups responsible to end these attacks at once and we underscore that Israel, like all nations, has a right to self-defense."

European officials have expressed their support for Israel and those affected by the attack in statements Wednesday.

“The news of an explosion on a bus in Jerusalem is shocking and deeply distressing,” said British Foreign Secretary William Hague. “I send my sincere condolences to all those who have been affected and my sympathy to the people of Israel as they come to terms with this news.”

“This appears to have been a callous and disgusting act of terrorism directed against innocent civilians which I condemn unreservedly. I would like to express the UK’s unwavering support for the people of Israel in the face of such horrific acts.”

France’s Foreign Minister Alain Juppe echoed these sentiments, condemning the attack “in the strongest possible terms,” and expressing sympathy with “the victims, their families and loved ones, and the Israeli authorities.”

“France reaffirms its solidarity with the Israel and the people murdered by this heinous act,” Juppe said in a statement.

J Street, the left-wing American pro-Israel group slammed in a Knesset session Monday morning issued a statement also condemning the attack "in the strongest possible terms."

The group's President Jeremy Ben-Ami and Board President Davidi Gilo issued a joint statement on Wednesday, saying their "hearts go out to the victims and their families and to the people of Israel who in recent days are experiencing once again an increase in terror and violence."

The statement quoted the late former Israeli Prime Minister Yitzhak Rabin, saying "we must fight terror as if there were no peace process, but pursue peace as if there were no terror."

Ben-Ami and Gilo then concluded the statement saying "even on the blackest of days like today, we remember his words and seek to carry out his legacy."

Wednesday's blast next to a crowded bus stop killed one woman and wounded more than 30 other people. It is the first major attack in Jerusalem in several years.
