JERUSALEM: In Jerusalem鈥檚 Old City there are dozens of churches, but as Christmas beckons there is just one Santa Claus 鈥� a towering Palestinian former basketball player.

Each December, the streets sparkle green and red as Christian pilgrims and others arrive to celebrate Christmas in Israeli-annexed east Jerusalem.

Seven years ago one resident, Issa Kassissieh, transformed the ground floor of his 700-year-old home into a grotto, complete with candy, mulled wine and a chance to sit on Santa鈥檚 lap.

Welcoming the season鈥檚 first visitors to Santa House, the red-suited and bearded Kassissieh belted out a 鈥淗o, ho, ho!鈥� at families queueing to see him.

鈥淲e are dealing with many religions here in Jerusalem. We have Muslims, Christians and Jews. I have all religions come to my house. I open my hands to everybody,鈥� said Kassissieh, himself a Christian.

Among the visitors were a group of Israeli tourists, as well as two priests who blessed the opening with prayers in Arabic and the ancient language of Aramaic.

At 1.9 meters tall, Kassissieh鈥檚 height served him well as captain of the Palestinian basketball squad, and does not seem to intimidate the children he towers over.

鈥淚鈥檓 not a Christian, but I still love Santa Claus ... We have a (Christmas) tree at home too,鈥� said eight-year-old Marwa, a Palestinian Muslim, grinning.

Visitors from around the world also lined up to sit on Santa鈥檚 lap, and to find out if they were on his naughty or nice list.

Alison Pargiter, from the US, waited with her children.

鈥淚t is important that our kids have fun, but we also want them to know the true story behind Christmas,鈥� the 52-year-old said.

At Santa House, Kassissieh said his young visitors have more modern concerns.

鈥淓very child asks me for an iPhone,鈥� he chuckled.

鈥淚 never promise anything, but I say: 鈥楲et鈥檚 pray, and if you鈥檙e on my good list, you will get it鈥�.鈥�

As a child, Kassissieh鈥檚 father would dress up as Santa for him and his two sisters.

Fifteen years ago, he found his father鈥檚 suit and decided to slip into the red velvet role.

But it has involved more than just putting on a suit.

Since then, he has attended the World Santa Claus Congress in Denmark and studied at a Santa school 鈥� yes, there is such a thing 鈥� in the US state of Colorado.

Kassissieh displayed a certificate from another center of Santa learning, the Charles W. Howard Santa Claus School, and said his training makes him Jerusalem鈥檚 only accredited Santa.

Based in Michigan, the Howard school traces its establishment to 1937, making it the world鈥檚 longest-running.

In his role, he is all too aware of the sensitivities in Jerusalem.
