The summit of the Arab League took place on Sunday in the Saudi city of Dhahran amid an escalation of the situation in Syria after US-led strikes on the country.
"Egypt opposes the use of any types of prohibited weapons on Syrian territory. In connection with this, we call for an international and transparent investigation using internationally recognized tools," the Egyptian president said in his welcoming speech at the Arab League summit.
Cairo is monitoring the escalating military tension in Syria with deep concern, Sisi said, adding that such a situation could threaten agreements on de-escalation zones.

The views of the Arab states on the US-led attack differ sharply: Qatar, Saudi Arabia, and other members of the Gulf Cooperation Council (GCC) supported the attacks, while Lebanon, Algeria and Iraq condemned them. The Iraqi Foreign Ministry called on the Arab League to work out a clear position in response to missile strikes by the United States and its allies on Syria in the course of the summit.
According to the Russian Defense Ministry, the three countries fired over 100 cruise and air-to-surface missiles, most of which were shot down by the Syrian air defense. According to Damascus, which has repeatedly said that it eliminated its chemical weapons stockpiles, the attack damaged Syrian infrastructure, and left three civilians injured.
Russian President Vladimir Putin stated on Saturday that the strikes had been carried out in violation of norms and principles of the international law.
