Did Indonesia minister shake US first lady's hand?

Once the wait for President Barack Obama's return was over, Indonesian anticipation turned to another question: Would a conservative Muslim government minister shake the first lady's hand?

He says he did, but not by choice. Footage on YouTube shows otherwise, sparking a debate that has lit up Facebook, Twitter and the rest of the blogosphere.

"I tried to prevent (being touched) with my hands but Mrs. Michelle held her hands too far toward me (so) we touched," Information Minister Tifatul Sembiring told tens of thousands of followers on Twitter.

While Indonesia has the largest Muslim population in the world, the vast majority practice a moderate form of the faith. But Sembiring has flaunted his piety, making a point of avoiding contact with women who are not related to him.

The minister was among the dignitaries in a receiving line that greeted the Obamas as they arrived in Jakarta on Tuesday - a homecoming of sorts for the president who spent part of his childhood here. Indonesians gathered around television sets across the country to watch the American president touch down. Children at the school he attended practiced a song dedicated to him just in case he visited.

In footage of the official welcome, Sembiring appeared to share his countrymen's enthusiasm. He smiled broadly as he shook the president's hand and then reached with both hands to grasp Michelle's. But later he said she forced their contact.

His denial was in a response to Tweets from Indonesians who noted the handshake, saying it called into question his long-standing claims that, as a good Muslim, he restricts his contact with women.

Many posts had a "gotchya" quality to them.

One female journalist - who said the minister had refused to shake her hand - gleefully noted that now he would no longer be able to wriggle out of it.
