The Spanish aid worker kidnapped in the Gaza Strip has been freed, Palestinian security sources said.
Roberto Vila, 34, who works for the media department of the Spanish aid group Cooperation Assembly for Peace, was abducted on Monday by four armed men from a car near the town of Deir Al-Balah in central Gaza and bundled into a yellow car.
Vila will be escorted out of the Gaza Strip by agents of the Palestinian preventative security services after being freed, the sources said on Monday without elaborating.
The same sources said they were aware of the identities of the kidnappers, but would not say any more.
Vila's seizure was the latest in a string of abductions targeting foreigners in the increasingly lawless Palestinian territory.
The gunmen who kidnapped him released Vila's French female colleague and two Palestinian assistants who had also been in the car with him.
No claim of responsibility for the abduction was made.
Palestinian prime minister Ismail Haniya, of the ruling Islamist Hamas movement, called the abduction immoral and demanded that the aid worker be released.
"We reject this kidnapping. It is immoral," he told reporters in Gaza City.
"I ask the people who kidnapped him to release him immediately. This is bad for Palestinian people."
The Al-Aqsa Brigades, a militant group close to president Mahmud Abbas's Fatah party, also condemned the abduction.
