London, Aug 9 - A desperate wish for a son may have led to the death of Pakistani Taliban leader Baitullah Mehsud, a British newspaper reported Sunday.

Mehsud was spending the night with his second wife in the village of Zangarha Wednesday when he was killed in an American drone attack, the Sunday Times said.

It said the 35-year-old Mehsud, who has four daughters by his first wife, took a second wife, the daughter of an influential cleric, last November.

The paper said the diabetic Mehsud, who had been feeling 'poorly', had taken a risk in spending the night at the house of second wife's father.

He had been seen by a local doctor, who had given Mehsud a glucose drip.

'In the end it may have been the desire for a son that led to the Taliban leader's demise,' said the report.
