A student has cycled 4,000km (2,500 miles) across West Africa, enduring arrests and blazing heat, for a spot at his dream university.

Mamadou Safayou Barry set off from Guinea for Egypt's prestigious Al-Azhar in May, hoping he would be accepted.

The 25-year-old cycled for four months through countries wracked by Islamist militants and coups.

He told the BBC he was "very, very" happy to have been given a scholarship when he finally reached Cairo.

The married father of one said although he could not afford the Islamic Studies course at Al-Azhar, or flights to Egypt, the university's reputation spurred him to take his chances on the epic trek through Mali, Burkina Faso, Togo, Benin, Niger and Chad.

Al-Azhar is one of the most influential centres for Sunni Islamic learning in the world. It's also one of the oldest, having been founded in the year AD670.

Mr Barry set off from his home "seeking Islamic knowledge" but experienced suspicion and adversity in some of the countries he biked through.

In Mali, Burkina Faso and Niger, attacks by Islamist militants on civilians are frequent and recent coups have led to political instability.
