Congress leader Manish Tewari on Saturday questioned whether India was "doing business" with terror outfit Islamic State (IS) in Libya.
"Happy two Indians released in Sirte LIbya pray for others. Ques- since (Foreign Minister) Sushma Swaraj claiming credit - is India doing business with IS in Libya," tweeted the former information and broadcasting minister.
"Since foreign minister seems to have direct "hotline" to IS or ISIS in Libya what happened to 57 people from Punjab, are they dead or alive FM," he also asked.
Four teachers, two of whom were released later, were held captive by the IS in Libya on Friday.
