Tens of thousands gathered here today for prayers for activists killed in Israel's deadly raid on aid ships bound for Gaza, condemning the Jewish state and shouting support for Hamas.
"Damn Israel! Israel is the angel of death!" chanted the crowd which overflowed the sprawling courtyard of the Fatih Mosque, waving Turkish and Palestinian flags.
The NTV news channel put the number of the mourners at
between 15,000 and 20,000.
"We are all soldiers of Hamas," the crowd shouted, referring to the Palestinian Islamist movement, which controls the Gaza Strip.
Nine people -- eight Turks and a US national of Turkish origin -- were killed in Monday's pre-dawn raid by Israeli forces on the Turkish ferry, Mavi Marmara, the lead ship in the aid flotilla aiming to break the crippling blockade of Gaza.
They were all shot dead, according to Turkish forensic experts, cited by the Anatolia news agency.
"May your martyrdom be blessed," read a huge banner in the colours of the Palestinian flag, hung on the wall surrounding the mosque courtyard.
The coffins of eight of the activists were laid on marble stands, covered with both Turkish and Palestinian flags, as several imams guided the mourners in the prayers.
One of the dead was to be buried in Istanbul later Thursday while the rest would be flown to their hometowns.
There will be a separate ceremony tomorrow for the last dead activist at another Istanbul mosque.
