Khaled Meshaal, 51, has been a senior political leader of Hamas, a Palestinian resistance movement, since 1995.

Currently living in exile in the Syrian capital of Damascus, he is a key engineer of Hamas' policy towards Israel.

But while he is a hero to many Palestinians, he is viewed by Israel, the US and other Western nations as the leader of an organisation committed to the Jewish state's destruction.

"It is true that in reality, there will be an entity or a state called Israel on the rest of Palestinian land," Meshaal has said.

"But I won't deal with it in terms of recognising or admitting it."

Political beginnings 

Born in 1956 from a Palestinian family in the West Bank, Meshaal was forced to live most of his life outside the Palestinian territories.

After Israel invaded the West Bank in 1967, Meshaal and his family left their village near Ramallah.

Like many at the time, thousands of Palestinians fled their hometown, fearful of the treatment they expected from their Israeli occupiers.

Meshaal's father found work in the Gulf state of Kuwait, when the country was known for being a hotbed of Arab nationalism and pro-Palestinian sentiment.

Soon after, Khaled Meshaal joined the Muslim Brotherhood, an influential political Muslim group.

He later enrolled as a student of Kuwait University, studied physics and founded a student group called the List of the Islamic Right.

Once Hamas was founded in 1987 after the first intifada (uprising), Meshaal led the Kuwait chapter of the organisation, but left the country when Iraq invaded in 1990.

Meshaal moved to the Jordanian capital, Amman, where he became head of the Hamas branch.

Assassination plot

In 1997, Benjamin Netanyahu, then Israeli prime minister, sent a two-man hit squad to kill Meshaal.

The agents attempted to inject a slow-acting lethal chemical into his ear on a public street, but the operation was botched and the men were soon arrested.

King Hussein, leader of Jordan, was outraged by the attack and rushed to negotiate a deal whereby Netanyahu sent over the antidote to the chemical.

Netanyahu had to release more than 40 Palestinians from Israeli prisons to secure the release of the two men who attacked Meshaal.

Sheikh Ahmed Yassin, Hamas' historic founder who served nine years in jail, was among the Palestinians released.

Yassin was killed in 2004 in an Israeli air raid on Gaza, while Abdel Aziz Rantissi, who co-founded Hamas with Yassin, was also killed by the Israeli military in the same year.

Meshaal's reputation as a committed figure within the Hamas leadership was cemented after the leaders were assassinated.

But he cannot return to the Palestinian territories for fear that he will be arrested or killed by Israeli authorities. As a result, he has lived in self-imposed exile since 2001.

'War of necessity'

Meshaal says that Hamas' policy is a direct reaction to Israel's invasion and subsequent occupation of Palestinian territories.

In an interview conducted by Al Jazeera's Hashem Ahelbarra, Meshaal asked: "Which came first, occupation or resistance?"

"Israel started the occupation and as a reaction, came the resistance," he said.
