The two Christian brothers who were left in a critical condition after suffering an attack by a local gang in Bethlehem are said to be "improving" and in a "stable condition," according to their church. 

On Friday, Daoud and Daher Nassar - who are part of the Evangelical Lutheran Church in Jordan and the Holy Land (ELCJHL) - were assaulted by 15 masked men in front of their families, leaving them with serious wounds on their heads and bodies.

In a statement posted on their church's Facebook page, the family expressed "tremendous gratitude" for the outpour of support from the local and international community.

"The Nassars thank God for their stable and improving health and continue to recover in the hospital. Pastor Munther and Bishop Azar has been with the family in support and counsel," the statement read. 

The Nassar family has been subject to continued harassment due to their 30-year-long battle to secure the legal ownership of the Tent of Nations, a Christian farm located south of Bethlehem surrounded by Israeli settlements. 

Over the years, they have been using the land as a ministry of reconciliation and peace and have welcomed many Palestinian and foreign peace groups. 

According to the church, the family has been reassured the Palestinian authorities are investigating the case. 

"We are optimistic about this commitment by the government, and implore our national leaders to resolve the dispute with the utmost of justice and urgency. 

"The family, as always, professes their steadfast commitment to non-violence. The hope the conflict ends soon in a peaceful way."

The statement concluded: "The church and the Nassar family could not be more grateful for the support shown for Daoud, Daher, and the Tent of Nations. The ELCJHL is in full support of the Nassar family, and asks for your continued prayers for Mr. Daoud and Daher, and justice over this prolonged fight for their land."
