Iran's suspect nuclear program will again be in the spotlight this weekend when negotiators from Iran and six international powers meet in Istanbul.

Iran was reluctant to have Turkey host the meeting, reflecting Iran's growing unhappiness with Turkish foreign policy moves, especially its call for regime change in Syria, Iran's key ally in the Arab world.

Analyst and columnist Yavuz Baydar says Turkey has stuck its neck out for Iran in the past, defending what it calls Iran's peaceful nuclear energy program and even voting against U.N. sanctions on Iran two years ago.

Days after it was acquired by Facebook for $1 billion, reports have emerged that Instagram now has more than 40 million users in its photo-sharing community. The gain, which was derived from the service's API, represents a spike of 10 million Instagram users added in the past 10 days, according to Venture Beat.
