You're live with me Martin and coming up we've got answers to

your questions about Paris, plus Minecraft expert Stampy

Let's start by trying to answer your questions

about what's been happening in France's capital city Paris.

On Friday an extremist group called Islamic State carried out several

attacks there and loads of you have been in touch to ask why

So, earlier I took your questions to a

man in the know - the BBC's security correspondent Frank Gardner.

First, a lot of people are asking why did Islamic State want to attack

France? The answer that Islamic State had given is that it is in

retaliation and revenge for their positions in Syria. What are the

soldiers and policemen doing to keep the people in Paris safe? The main

point of the soldiers and police on the streets are to reassure the

public and to put off any terrorists who might think of maybe attacking

again. When they see the police with the guns, hopefully they won't want

to attack. That is the main purpose of it. Is it likely that the UK will

get attacked and if so, are we prepared for it? That is something

lots of other children have been asking. They have been a number of

attempted attacks, people trying to do attacks in this country. Nothing

as big as in Paris, but smaller and still nasty. The police have been

able to stop them. They say sooner or later, something might get

through. What I would say is the chances of you or me or any of your

friends being caught up in it are very small. Tiny, in fact. There is

a high chance there will be an attack in Britain somewhere,

probably quite small, but the chances of you being caught up in it

are quite small, so don't change your way of life.

Well, you can see Frank answering more questions right now

That's also where to find out loads more about what's happening

And there's lots of advice on there, too,

But now, if you love Minecraft, then listen up.

A type of in-game bullying called griefing has been leaving lots

So Ayshah's been to find out more with the help of Minecraft expert.

If you are not sure what griefing is, here is Stampy with an

explanation. It is when someone does something in intentionally mean to

someone in Minecraft or anywhere else. Griefing can become bullying.

It can be a joke of, I have hidden your items or set up a trap as you

go into your house, but if someone is not having fun and it is a group

of people griefing one person, it is a bad thing. Mike Ross users told me

that griefing stories. I was going about my business and someone took

all my stuff. Someone looted all my chest and do my house down. So why

do people do it? I think they do it for the laughs, or if someone builds

a house they found better than theirs, they just want to get rid of

it. They just want to mess around with people and just be annoying. It

is what you work on for hours and you don't want it to be destroyed.

How can you avoid griefing? I think the problem is when griefing crosses

over from what you do in gameplay and turns into messages. If someone

is writing nicely things and more or less bullying you, it is wrong. You

can make it that only your friends can join or they have two apply to

join. The safest way to avoid griefing is to just play with the

people that you know.
