US family of captive asks al-Qaeda to free him

Family members of a US development expert kidnapped in Pakistan by al-Qaeda more than two years ago say a recently released video and letter haven't convinced them he's alive.

His family released a statement Thursday asking for "date-specific" confirmation that Warren Weinstein is alive and well.

Weinstein appeared in a video sent last week to reporters in Pakistan, appealing to US President Barack Obama to negotiate his release. It was the first video of Weinstein since September 2012. There was no indication of when it was made. (AP)
