As police continue to hunt a fugitive in connection with the Brussels terror attacks, more eyewitness accounts have emerged.

Airport worker Alphonse Youla is reported to have been putting security wrapping around suitcases at the Belgian capital's Zaventem Airport when the two explosions struck.

Outside the airport, Mr Youla spoke to reporters with his uniform still marked with blood.

"I heard a man shout some Arabic words then an explosion ... then a second explosion, a massive explosion, much bigger," he said.

He managed to help two elderly people into a lift to safety but described the chaos in the terminal.

Mr Youla added: "It was a horror. I saw at least seven people dead. There was blood. People had lost legs. You could see their bodies but no legs."

Brazilian-born basketball player Sebastien Bellin, 37,was pictured lying on the airport floor. He was thrown 6ft into the air by the explosion and was injured when shrapnel entered his left leg and right hip.

Mr Bellin, a father of two who plays for the Belgian national team, has had surgery, his father, Jean Bellin, told CNN.

He said: "My son is doing well, considering. He went through his first operation today. Because he was left for about an hour on the floor in the airport in Brussels, he lost a lot of blood.

"So they stabilised him and now he is going to go through another operation.

"I spoke with him twice. He is obviously stunned. The first words out of his mouth were 'You wouldn't believe the carnage I saw around'."

The manhunt for the unidentified third suspect is believed to be Belgium's biggest police operation.

As the country entered the second of three days of national mourning, more shocking pictures of the impact of the attacks have also come to light.

A copy of an X-ray thought to be of an unnamed victim of the attack shows a 3in (7.6cm) bolt close to the patient's heart.

The photograph is believed to have come from the Military Hospital in Neder-over-Heembeek in the northern part of the Belgian capital.

One of the photographs which symbolised the chaos of Tuesday's attacks showed a woman sitting on airport seats, covered in dust and blood, with her distinctive yellow uniform shredded.

It was taken by journalist Ketevan Kardava, a special correspondent for the Georgian Public Broadcaster, who is based in Brussels.

India-based Jet Airways confirmed that the woman was one of its staff members.
