An attacker who fired a crossbow at a police officer guarding the Israeli embassy in Belgrade was shot dead on Saturday in what President Aleksandar Vucic called a terrorist attack against Serbia.

No embassy staff were wounded in the attack, the Israeli foreign ministry said, and the policeman was in a stable condition in hospital following surgery to remove an arrow from his neck, Vucic said.

Vucic named the attacker as Salahudin Zujovic, a man from central Serbia who had converted to Islam from Serbian Orthodox Christianity, and said he had worked with an accomplice who remained at large.

"We are looking for another person," Vucic told reporters after visiting the wounded policeman. "We will secure all diplomatic missions and also guarantee safety and security."

The pair were being tracked by Serbian security agencies prior to Saturday's attack but there was not enough evidence to detain them, Vucic added.

Earlier in the day, interior minister Ivica Dacic said the policeman who was attacked had fired several shots at the assailant, killing him.

He said a number of people had been arrested on suspicion of being connected to the attack and investigators were looking into possible links with followers of the puritanical Sunni Muslim Wahhabi sect.

Israel's foreign ministry said there had been "an attempted terrorist attack in the vicinity of the Israeli embassy in Belgrade".

"The embassy is closed and no employee of the embassy was injured. The circumstances of the incident are being investigated," it said in a statement.

Israel-linked institutions around the world have been on high alert for attacks and protests since Israel launched its war to eliminate Hamas in the Palestinian enclave of Gaza, after the Islamist militant group led deadly attacks on southern Israel on Oct. 7, 2023.

The police officer was in a guard house and the attacker had approached him several times asking him where a museum was, before taking the crossbow from a bag and firing it at him, Dacic said.

Police investigators in white forensic suits surrounded the attacker's body outside the building, which was swarmed with police vehicles.

In 2009, a Serbian court sentenced four Muslims who were followers of the Wahhabi sect to prison for plotting to attack a football stadium in a southwestern Serbian town where the majority of the population are moderate Muslims.

At least 34 people, including two babies were killed when a contraband fuel depot exploded into flames in southern Benin near the border with Nigeria on Saturday.

According to Beninese Interior Minister Alassane Seidou, “a serious fire occurred in the town of Seme Podji. Another 20 people were seriously wounded in the incident.”

"I can't really give you the cause of the fire, but there is a large gasoline warehouse here and cars, tricycles and motorcycles come from morning to evening,” he added.

Nigeria is a main oil and gas producer where fuel smuggling is very common along its borders, particularly when the government maintains a subsidy to keep fuel prices low.

The majority of the victims were burnt and they could not be not be identified.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
