A shooting rampage at a police training center that killed five people, including two American instructors, took place in a dining hall in the compound, the Jordanian government spokesman said Tuesday.
Monday's shooting also killed a South African contractor and two Jordanians who worked as translators for the foreign instructors at the facility. Six people were wounded, including two Americans.
Officials have released few details, but government spokesman Mohammed Momani said Tuesday that the attacker was a Jordanian police captain and was killed by security forces.
Images circulating on social media showed three large pools of blood on the floor of a room with at least two tables, one of them bearing plates of food.
It was not clear if there was a political motive to the shooting spree.
Concern has swirled in pro-Western Jordan over possible revenge attacks by Islamic militants since the country assumed a high-level role in the U.S.-led military campaign against the Islamic State extremist group, which controls large areas of neighboring Syria and Iraq.
The government has not released the name of the attacker. A former parliament member, Suleiman Saed, has said security forces told him a relative, 29-year-old police Cpt. Anwar Abu Zaid, was the assailant. Abu Zaid's family has said he was not an extremist.
The two Jordanian translators were to be buried later Tuesday and Wednesday.
Translator Awni al-Akrabawi, 44, worked at the training center for the past three years and had close ties with his American colleagues, said a relative, Khairallah al-Akrabawi.
Al-Akrabawi, a father of four, had lived in the United States for more than a decade and spoke fluent English, said his relative, a former parliament member. His funeral was to take place Wednesday to enable U.S. relatives to reach Jordan, Khairallah al-Akrabawi said.
The U.S. State Department has said the two Americans killed in the attack worked for DynCorp International, a major military contractor, in a program funded by the State Department's Bureau of Diplomatic Security and Bureau of International Narcotics and Law Enforcement. The two wounded Americans are also civilians, the State Department said.
Thousands of police officers from the region, including the Palestinian territories, have undergone training at the Jordanian-run center on the outskirts of the Jordanian capital of Amman.
