Mid-East protests: Your stories
Demonstrators in a number of countries including Saudi Arabia, Bahrain and Egypt continued to take to the streets on Friday.
In Saudi Arabia, amateur video showed that demonstrators were out in force in Qatif although BBC News website readers got in touch to say they believed heavy thunderstorms could have an impact on the protests planned in Riyadh.

The authorities here have made their stance very clear and any indication of sedition or descent will not be tolerated.
I've just been outside to the local supermarket on Pepsi-Cola Road and everywhere seems very quiet and subdued.
There was a dust storm last night that still hasn't fully dispersed and there's a thunderstorm just starting. This will certainly have had an influence, and kept people at home.
We were out for dinner last night about a mile from Olaya Street and the Al Faisaliah Tower. The mall was almost empty and the restaurants were the same.
The police presence was very heavy but, being a white westerner, they tend to leave me alone.
I wasn't sure whether or not the demonstrations would happen but I made preparations anyway. I withdrew as much cash as could over the past few days so that I could pay for a plane ticket home.
One of the problems that has happened in other countries, when the internet has been turned off, is that flight check-in and booking systems stop working. I've experienced problems here before when there was flooding that knocked out parts of the network.
The advice from the FCO was just to stay at home and avoid public gatherings. As such, I've stayed close to the hotel all day. I'm curious to see what the centre of the city is like but I have no intention of venturing there anytime soon.
Other comments from Saudi Arabia
I am in Saudi Arabia, but I will not participate in any mass protest. Why? I don't believe Saudi Arabia needs it and will benefit from it. What the country needs is a dialogue and one of royals in position, HRH Prince Saud, already signified a positive opinion about this. The minority should seek serious, transparent and meaningful dialogue to air their concerns and complaints. The government should listen and consider and act upon what is workable and beneficial for all its citizens. Yusuf, Jeddah
The rulers of Saudi Arabia seem to be unrelenting and are hell bent on suppressing dissent. If this continues people will lose confidence and are bound to revolt violently. Abdulla, Qatif
I am a Saudi women, and while I do want positive change not only in my country but around the world, I do not believe "protests" are the way. Best example is what is happening in other countries. Open dialogue and intelligent organised communication between the public and government officials is the best method to get sound and unbiased results. The people of Saudi Arabia love King Abdullah but are dissatisfied with various officials standing between him and the public who are not working fully for the well being of the people and the best interest of the country.

Protesters are not being allowed access to the site where demonstrators are supposed to congregate, with those who make a fuss or insist being arrested at gunpoint at checkpoints. Websites we can access have little on what is happening in Saudi Arabia. Simon, Riyadh

We are safe at the moment in Al-Beida but we are worried about Ras Lanuf and what is happening there. They are trying to bomb unarmed people. Our people don't have the weapons that Gaddafi does.
We are worried. My brothers and my neighbours - some of whom are just 16-years-old and children - have gone to Ras Lanuf to show their support.
The Omar Al-Mukhtar University here in Al-Beida has closed and I am aware that many students have gone to the front line to fight for their independence.
We are praying all the time. We know of so many women and children who have died.
This is nothing to do with al Qaeda. Gaddafi is a dictator and he needs to go.
The people in Europe and the rest of the world need to do more to help us. Too many people are dying.
I was at the Peal Roundabout pro-democracy demonstration today, which was peaceful.
But there was another demonstration taking place where I heard there was some trouble.
It was in Riffa which is about five miles away. There was a march to the royal palace and pro-government and pro-democracy supporters fought each other with a number of people ending up in hospital.
At Pearl Roundabout, the demonstrators were shouting things like "Sunni and Shia together", "peace now", "King Hamad Out" and "Khalifa out".
The atmosphere there was calm and lots of speeches took place.
