More uncertainty and increased war activities in Libya have heightened tension in Tripoli as rebels fight to control Libya. The fight over Tripoli has left over 174 dead so far in the last few day.

At least 174 people have been killed and 758 have been wounded in the battle for control of the Libyan capital Tripoli, according to the World Health Organization.

Among the dead are 14 civilians and 36 have been wounded, WHO spokesman Tarik Jasarevic has said.

Fighting broke out on 4 April when forces under Gen Khalifa Haftar advanced from the east with the aim of taking Tripoli.

On Monday the UN envoy to Libya Ghassan Salamé expressed his growing concern that the battle for the capital is escalating.

Mr Salamé said his worst fear was that foreign powers may become directly involved with more advanced weaponry.
