Only days after NBC removed him from its coverage of the fighting in Gaza, the correspondent Ayman Mohyeldin will be reinstated and sent back into the region, the network said Friday evening.

The decision to pull Mr. Mohyeldin off the story, after he witnessed an Israeli air attack that killed four Palestinian children and then posted remarks on Twitter about it, prompted a round of questions, and much criticism of NBC among Internet commenters. Some accused the network of reacting to pressure from the Israeli side of the conflict. Mr. Mohyeldin is an Egyptian-American who previously worked for the cable news channel Al Jazeera English.

Other commenters speculated that NBC might have felt that Mr. Mohyeldin showed too much empathy in his social media comments. At one point he wrote, “just spent 45 min see family relative after relative learn that their children have been killed in #Israeli shelling of #Gaza port #horror.”

When it removed Mr. Mohyeldin, NBC did not give a reason for its decision, which was first reported by the news sites TVNewser and The Intercept, other than unspecified security concerns.
