This post is part of our special coverage Yemen Protests 2011.

Thousands of protesters are marching across Yemen today, Tuesday, in a Day of Wrath to condemn Friday's attacks on protests in Aden, and to call for the end of the Ali Abdullah Saleh regime. According to Amnesty International, clashes on Friday claimed the lives of four Yemenis, and left 26 wounded.

Saleh's call for national dialogue to end protests that have been taking place for weeks have been snubbed by the opposition, who only want him and his regime out of power.

In the capital Sana'a, protests by both anti and pro-Saleh groups took place, while Saleh, who has been in power since 1978, accused both Israel and the US for standing behind the current wave of protests across the Arab world.

On Twitter, the world continues to watch and react to developments in Yemen. Following are some reactions from Yemenis and tweeple paying close attention to developments on the ground:

@Dima_Khatib: #Yemen government says will form a national unity government within 24hours. Opposition says: no thank you. We want to overthrow regime!

@Dima_Khatib: Opposition parties in #Yemen rejected government's offer to dialogue (at last) and now want a revolution with the people !!!

@steveturtle: #Yemen's Saleh accuses Israel and US of fomenting revolts. Clearly he hasn't been listening to Gadaffi. He knows its all Al-Qaeda and drugs

@Sareh1357: That's funny! “AJA: Yemeni president #Saleh: What's happening in the Arab world right now is being orchestrated by Tel Aviv & White House.”

@lars_akerhaug: Ok, mr. Saleh, lay off the red pills. One madman is enough.
