Factors that break and don't break the fast

Using scented tissues and Makkah oil while fasting

Q: I have two questions:

1. During Ramadaan, while fasting I had a terrible migraine. I applied Makkah oil (green box medicine) on my forehead. Would the smell break my fast?

2. In Ramadhaan, while fasting I was in Australia. I had a running nose and used something like a Vicks scented tissue. I didn't know it was scented. Then I was confused where the smell came from so I blew my nose again. Only then I realized it was from the tissue. I think I could feel the smell going down in my nose. Is my roza accepted or must I make qadha?

Fasting while travelling

Q:

1. I have read that one can only miss his fast if one is a traveller at sehri time. What will be the ruling of an individual who is travelling abroad but his  light is at afternoon time (meaning he is still at home at sehri time)?

2. If that person needs to fast, how will he do Iftar because different countries have different iftar times.

3. Also, will putting Vicks under the nose and sniffing it throurg out the day break one's fast? I have read that it doesn't because it does not have a body. Will that have the same ruling if one was to sniff Vicks from a tissue (i.e. putting some vicks on a tissue and then inhaling the subtance form the tissue?

Breaking the fast through masturbating

Q:

1) If a person intentionally keeps masturbating and ejaculating during whole ramazan since he fasted 1st roza of his life so will masturbating and ejaculating broke his roza?

2) If rozas have broken due to masturbating will he have to done qaza for each roza or he will have to pay kaffara for each roza?

3) What is the qaza and kaffara of one broken roza intentionally?
