Demonstrations are taking place around the world in a show of unity with protesters fighting for political change in Egypt.
In Turkey between 200 and 400 protesters held a demonstration outside the Fatih Mosque in central Istanbul after Friday prayers to lend their voices to the Egyptian cause.
Anita McNaught, Al Jazeera's correspondent in Turkey, said the mosque had become a focal point for activism since Israeli commandos raided a Turkish ship headed to Gaza last year.
"It is very much the organisations that we saw rise to prominence following the Israeli attack on the Mavi Marmara that have taken on the streets today to lend their voices in solidarity with the Egyptians," she said.
A simultaneous rally of about 50 people was also held in Ankara, the Turkish capital, where up to 50 people gathered outside the Egyptian embassy.
In London, Britain's capital, around 50 protesters are gathering outside the Egyptian embassy to add their voices to those calling for Hosni Mubarak, the president, and his government, to step down.
Abdullah Ali, a 26-year-old demonstrator at the rally in London, told Al Jazeera they were asking for "free democratic elections".
"I think the Egyptian population have had enough. They've seen what happened in Tunisia and how you can bring about a change. What we are asking for is Mubarak, father and son, to leave."
Many Tunisians, who saw major and violent protests topple the leadership of its president earlier this month, have also expressed solidarity with Egypt, saying that they hoped their revolution would spark events around the Arab world.
Around 50 people are holding a demonstration outside the Egyptian embassy in Tunis, the capital, brandishing placards with slogans reading "Mubarak Out!" and "Freedom".
"We are here to say that the Tunisian people are behind the Egyptian people. They have suffered in the way that we suffered. It's time for change," Monia Mechri, one of the protesters, was quoted by the AFP news agency.
The Progressive Democratic Party, a former opposition group that has now joined Tunisia's interim government, said Egypt had "called in the hour of change for an end to injustice and dictatorship".
"The Egyptian people supported the Tunisian people's revolution. Our heart is with you and our voices never cease to pray for victory," it added in a statement.
Ahmed, a blogger and activist at the rally told Al Jazeera that what has happened in Egypt is "very great".
"Now democracy will be ... one effect in the Arabic world," he said.
He said activists in Tunisia had used Facebook to message people in Egypt with advice on how to tackle police tactics during their protests.
Demonstrations have also been held outside the Egyptian embassy in Doha, the Qatari capital, where political demonstrations are a rare event.
