Hamas urged UNESCO to protect historic buildings in the Gaza Strip on Friday, saying Israel's assault had left the Palestinian territory's oldest church, last hammam baths and treasured mosques in ruins. Footage and images posted on social media on Friday appeared to show the Great Omari Mosque, the largest and oldest in Gaza City, reduced to rubble. Only the minaret appeared to be intact, with the surroundings -- which have been a Christian or Muslim holy site since at least the fifth century -- shattered, AFP reported.
