Prime Minister Binyamin Netanyahu spoke on the telephone with Egyptian President Hosni Mubarak and Jordanian King Abdullah on Monday about the rocket attacks which struck Jordan and Israel earlier in the day.
"The attacks perpetrated on innocent citizens of Jordan and Israel were carried out by terrorists that want to thwart the peace process," said Netanyahu in a statement released Monday.
"All of the countries in the region who want peace need to fight against these forces in order to expel terror and bring peace closer," he added.
Jordan condemned Monday the firing of a rocket that struck near the Intercontinental Hotel in Aqaba in which a Jordanian man was killed and four others were injured. The rocket was one of six which struck the area, including a second rocket in Jordan, one near Eilat, two in the Red Sea and one in the Sinai Peninsula.
In a statement released by the Jordanian Information Ministry the rocket attack was called a "terror attack." Jordan promised to continue in its war against terror.
A Jordanian taxi driver injured in the attack died of his wounds Monday.
The rockets were almost definitely fired from Sinai, according to sources in the defense establishment quoted by Israel Radio. The rockets were suspected to have been launched from the Sinai Peninsula by Islamic Jihad, however Egyptian officials denied the assessment.
"No rockets were launched from the Sinai," said Egyptian sources. "To launch rockets from Egypt, it takes equipment and complicated logistical preparations. It is impossible, since the Sinai Peninsula has heavy security."
BBC Arabic reported that Egyptian security forces were scouring the area around Taba and Nuweiba, but had found no sign of a rocket launch.
Eilat Police sappers said that the Grad-type Katyushas were Iranian-made, with a range of some 20 kilometers. The rockets reportedly weighed 6 kilograms each.
According to an IDF statement, soldiers were scouring the area to determine the source of the attacks, which was unclear. The IDF was in contact with the Jordanian and Egyptian armies regarding the incident.
The US condemned the attacks on Monday, calling the actions "deplorable," AFP reported.
US State Department spokesman Philip Crowley told reporters that the attacks seemed to be an attempt to sabotage peace talks between Israel and the Palestinian Authority.
"At a point where we are hoping to see direct negotiations begin as soon as possible to address the core concerns, it's not surprising that you have others who are taking actions to try to inhibit that kind of progress," said Crowley.
He added that the US has "strong suspicions" about who is responsible for the attacks, but gave no further elaboration.
